Don't force scaling on 2D copy sources (#2701)
Some games (GameMaker Studio) build texture atlases out of sprites during initialization, using the 2D copy method. These copies are done from textures loaded into memory, not rendered, so they are not scaled to begin with.

I had set srcTexture in these copies to force scaling, but really it only needs to scale if the texture already exists and was scaled by rendering or something else. I just set that to false, so it doesn't change if the texture is scaled or not. This will also avoid the destination being scaled if the source wasn't. The copy can handle mismatching scales just fine.

This prevents scaling artifacts in GMS games, and maybe others (not Super Mario Maker 2, that has another issue).

Replace CacheResourceWrite with more general "precise" write (#2684)
* Replace CacheResourceWrite with more general "precise" write

The goal of CacheResourceWrite was to notify GPU resources when they were modified directly, by looking up the modified address/size in a structure and calling a method on each resource. The downside of this is that each resource cache has to be queried individually, they all have to implement their own way to do this, and it can only signal to resources using the same PhysicalMemory instance.

This PR adds the ability to signal a write as "precise" on the tracking, which signals a special handler (if present) which can be used to avoid unnecessary flush actions, or maybe even more. For buffers, precise writes specifically do not flush, and instead punch a hole in the modified range list to indicate that the data on GPU has been replaced.

The downside is that precise actions must ignore the page protection bits and always signal - as they need to notify the target resource to ignore the sequence number optimization.

I had to reintroduce the sequence number increment after I2M, as removing it was causing issues in rabbids kingdom battle. However - all resources modified by I2M are notified directly to lower their sequence number, so the problem is likely that another unrelated resource is not being properly updated. Thankfully, doing this does not affect performance in the games I tested.

This should fix regressions from #2624. Test any games that were broken by that. (RF4, rabbids kingdom battle)

I've also added a sequence number increment to ThreedClass.IncrementSyncpoint, as it seems to fix buffer corruption in OpenGL homebrew. (this was a regression from removing sequence number increment from constant buffer update - another unrelated resource thing)

* Add tests.

* Add XML docs for GpuRegionHandle

* Skip UpdateProtection if only precise actions were called

This allows precise actions to skip reprotection costs.

Fast path for Inline2Memory buffer write that skips write tracking (#2624)
* Fast path for Inline2Memory buffer write

This PR adds a method to PhysicalMemory that attempts to write all cached resources directly, so that memory tracking can be avoided. The goal of this is both to avoid flushing buffer data, and to avoid raising the sequence number when data is written, which causes buffer and texture handles to be re-checked.

This currently only targets buffers, with a side check on textures that falls back to a tracked write if any exist within the target range. It's not expected to write textures from here - this is just a mechanism to protect us if someone does decide to do that. It's possible to add a fast path for this in future (and for ShaderCache, once that starts using tracking)

The forced read before inline2memory begins has been skipped, as the data is fully written when the transfer is completed anyways. This allows us to flush on read in emergency situations, but still write the new data over the flushed data.

Improves performance on Xenoblade 2 and DE, which was flushing buffer data on the GPU thread when trying to write compute data. May improve performance in other games that write SSBOs from compute, and update data in the same/nearby pages often.

Super Smash Bros Ultimate should probably be tested to make sure the vertex explosions haven't returned, as I think that's what this AdvanceSequence was for.

* ForceDirty before write, to make sure data does not flush over the new write

Lift textures in the AutoDeleteCache for all modifications. (#2615)
* Lift textures in the AutoDeleteCache for all modifications.

Before, this would only apply to render targets and texture blit. Now it applies to image stores, the fast dma copy path and any other type of modification.

Image store always at least has one reference in the texture pool, so the function of the AutoDeleteCache keeping textures _alive_ is not useful, but a very important function for a while has been its use to flush textures in order of modification when they are dereferenced, so that their data is not lost.

Before, textures populated using image stores were being dereferenced and reloaded as garbage. Now, when these textures are dereferenced, their data will be put back into memory, and everything stays intact.

Fixes lighting breaking when switching levels in THPS1+2, and potentially some more UE4 games. I've tested a bunch more games for regressions and performance impact, but they all seem fine.

* Lift copy srcTexture so that it doesn't remain referenceless

* Perform lift before reference count change on unbind.

It's important to lift on unbind as that is the moment the texture was truly last modified, but definitely not after releasing every single reference.

Add a Multithreading layer for the GAL, multi-thread shader compilation at runtime (#2501)
* Initial Implementation

About as fast as nvidia GL multithreading, can be improved with faster command queuing.

* Struct based command list

Speeds up a bit. Still a lot of time lost to resource copy.

* Do shader init while the render thread is active.

* Introduce circular span pool V1

Ideally should be able to use structs instead of references for storing these spans on commands. Will try that next.

* Refactor SpanRef some more

Use a struct to represent SpanRef, rather than a reference.

* Flush buffers on background thread

* Use a span for UpdateRenderScale.

Much faster than copying the array.

* Calculate command size using reflection

* WIP parallel shaders

* Some minor optimisation

* Only 2 max refs per command now.

The command with 3 refs is gone. 😌

* Don't cast on the GPU side

* Remove redundant casts, force sync on window present

* Fix Shader Cache

* Fix host shader save.

* Fixup to work with new renderer stuff

* Make command Run static, use array of delegates as lookup

Profile says this takes less time than the previous way.

* Bring up to date

* Add settings toggle. Fix Muiltithreading Off mode.

* Fix warning.

* Release tracking lock for flushes

* Fix Conditional Render fast path with threaded gal

* Make handle iteration safe when releasing the lock

This is mostly temporary.

* Attempt to set backend threading on driver

Only really works on nvidia before launching a game.

* Fix race condition with BufferModifiedRangeList, exceptions in tracking actions

* Update buffer set commands

* Some cleanup

* Only use stutter workaround when using opengl renderer non-threaded

* Add host-conditional reservation of counter events

There has always been the possibility that conditional rendering could use a query object just as it is disposed by the counter queue. This change makes it so that when the host decides to use host conditional rendering, the query object is reserved so that it cannot be deleted. Counter events can optionally start reserved, as the threaded implementation can reserve them before the backend creates them, and there would otherwise be a short amount of time where the counter queue could dispose the event before a call to reserve it could be made.

* Address Feedback

* Make counter flush tracked again.

Hopefully does not cause any issues this time.

* Wait for FlushTo on the main queue thread.

Currently assumes only one thread will want to FlushTo (in this case, the GPU thread)

* Add SDL2 headless integration

* Add HLE macro commands.

On by default. Would be good to turn this off for untrusted code (homebrew, exefs mods) and give the user the option to turn it on manually, though that requires some UI work.

* Improve Buffer Textures and flush Image Stores

Fixes a number of issues with buffer textures:

- Reworked Buffer Textures to create their buffers in the TextureManager, then bind them with the BufferManager later.
  - Fixes an issue where a buffer texture's buffer could be invalidated after it is bound, but before use.
- Fixed width unpacking for large buffer textures. The width is now 32-bit rather than 16.
- Force buffer textures to be rebound whenever any buffer is created, as using the handle id wasn't reliable, and the cost of binding isn't too high.

Fixes vertex explosions and flickering animations in UE4 games.

Use "Screen Scissor" as size hint for render targets (#1703)
"Screen scissor" is the minimum size of all render targets, and is set when any render target is bound on NVN or OpenGL. Since it works on all active texture's real sizes, it is therefore more reliable than viewport 0's width, and is actually set before clear.

This fixes a regression with Hyrule Warriors: Age Of Calamity's cubemaps, which did not set viewport dimensions before clear. This resulted in attempting to create a cubemap with rectangular sides, which is logically and physically impossible. (also it just fails)
