This greatly reduces memory usage in games that aggressively reuse memory without removing dead textures from the pool, such as the Xenoblade games, UE3 games, and to a lesser extent, UE4/unity games.
This change stops memory usage from ballooning in xenoblade and some other games. It will also reduce texture view/dependency complexity in some games - for example in MK8D it will reduce the number of surface copies between lighting cubemaps generated for actors.
There shouldn't be any performance impact from doing this, though the deletion and creation of textures could be improved by improving the OpenGL texture storage cache, which is very simple and limited right now. This will be improved in future.
Another potential error has been fixed with the texture cache, which could prevent data loss when data is interchangably written to textures from both the GPU and CPU. It was possible that the dirty flag for a texture would be consumed without the data being synchronized on next use, due to the old overlap check. This check no longer consumes the dirty flag.
Please test a bunch of games to make sure they still work, and there are no performance regressions.
Got this the wrong way round - was causing games to try synchronize mipmap levels of like 52 on a 3d texture with 6 levels. Also, corrected the variable name in the method that _was_ working.

* Return mapped buffer pointer directly for flush, WriteableRegion for textures
A few changes here to generally improve performance, even for platforms not using the persistent buffer flush.
- Texture and buffer flush now return a ReadOnlySpan<byte>. It's guaranteed that this span is pinned in memory, but it will be overwritten on the next flush from that thread, so it is expected that the data is used before calling again.
- As a result, persistent mappings no longer copy to a new array - rather the persistent map is returned directly as a Span<>. A similar host array is used for the glGet flushes instead of allocating new arrays each time.
- Texture flushes now do their layout conversion into a WriteableRegion when the texture is not MultiRange, which allows the flush to happen directly into guest memory rather than into a temporary span, then copied over. This avoids another copy when doing layout conversion.
Overall, this saves 1 data copy for buffer flush, 1 copy for linear textures with matching source/target stride, and 2 copies for block textures or linear textures with mismatching strides.

* Honour copy dependencies when switching render target
When switching from one render target to another, when both have a copy dependency to each other, a copy can be deferred on the second target when unbinding the first.
Before, this would not be honoured before binding the new texture, so the copy would stay deferred until the render targets change again, at which point it would copy in old data and essentially clear all the draws done during that time.
This change runs synchronize memory to make sure that copies are honoured. This can cause a redundant copy, but it's better than it breaking for now.
This should fix miiedit on AMD/Intel GPUs on windows. May fix other games, or perhaps rare copy dependency bugs on NVIDIA too.

* Compare aligned size for largest mip level when considering sampler resize
When selecting a texture that's a view for a sampler resize, we should take care that resizing it doesn't change the aligned size of any larger mip levels.
This PR covers two cases:
- When creating a view of the texture, we check that the aligned size of the view shifted up to level 0 still matches the aligned size of the container. If it does not, a copy dependency is created rather than resizing.
- When searching for a texture for sampler, textures that do _not_ match our aligned size when both are shifted up by its base level are not considered an exact match, as resizing the found texture will cause the mip 0 aligned size to change. It will create a copy dependency view instead.
Fixes graphical errors and crashes (on flush) in various Unity games that use render-to-texture.
* Move shared code to its own method.
* Pass CbufSlot when getting info from the texture descriptor
Fixes some issues with bindless textures, when CbufSlot is not equal to the current TextureBufferIndex.
Specifically fixes a random chance of full screen colour flickering in Super Mario Party.
* Apply suggestions from code review
Oops

* Improve linear texture compatibility rules
Fixes an issue where small or width-aligned (rather than byte aligned) textures would fail to create a view of existing data. Creates a copy dependency as size change may be risky.
* Minor cleanup
* Remove Size Change for Copy Depenedencies
The copy to the target (potentially different sized) texture can properly deal with cropping by itself.
* Move StrideAlignment and GobAlignment into Constants
* 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.
* Set ImageStore flag... for ImageStore.
* Check the offset and size.
* Improve handling for unmapped GPU resources
- Fixed a memory tracking bug that would set protection on empty PTEs
- When a texture's memory is (partially) unmapped, all pool references are forcibly removed and the texture must be rediscovered to draw with it. This will also force the texture discovery to always compare the texture's range for a match.
- RegionHandles now know if they are unmapped, and automatically unset their dirty flag when unmapped.
- Partial texture sync now loads only the region of texture that has been modified. Unmapped memory tracking handles cause dirty flags for a texture group handle to be ignored.
This greatly improves the emulator's stability for newer UE4 games.

* Allow copy destination to have a different scale from source
Will result in more scaled copy destinations, but allows scaling in some games that copy textures to the output framebuffer.
* Support copying multiple levels/layers
Uses glFramebufferTextureLayer to copy multiple layers, copies levels individually (and scales the regions).
