This fixes a rare bug where reporting a counter for a region containing 0 draws could deadlock the GPU. If this write overlaps with a tracking action, then the GPU could end up waiting on something that it's meant to do in the future, so it would just get stuck.
Before, this reported immediately and wrote the result to guest memory (tracked) from the backend thread.
The backend thread cannot be allowed to trigger read actions that wait on the GPU, as it will end up waiting on itself, and never advancing.
In the case of backend multithreading's `SyncMap`, it would try to wait for a backend sync object that does not yet exist, as the sync object would exist according to the GPU and tracking, but it has not yet been created by the backend (and never will be, since it's stuck).
The fix is to queue the 0 draw event just like any other, its _bufferMap value is just forced to 0.
This affects games that use Conditional Rendering: SMO, Splatoon 2, MK8. Was generally indicated by a red message in log saying that the query result timed out after 5000 tries, but not always the cause.

* bsd: Revamp API and make socket abstract
This part of the code was really ancient and needed some love.
As such this commit aims at separating the socket core logic from the IClient class and make it uses more modern APIs to read/write/parse data.
* Address gdkchan's comment
* Move TryConvertSocketOption to WinSockHelper
* Allow reusing old fds and add missing locks around SocketInternal and ShutdownAllSockets
* bsd: ton of changes
- Make sockets per process
- Implement eventfds
- Rework Poll for support of eventfds
- Handle protocol auto selection by type (used by gRPC)
- Handle IPv6 socket creation
* Address most of gdkchan comments
* Fix inverted read logic for BSD socket read
* bsd: Make Poll abstract via IBsdSocketPollManager
* bsd: Improve naming of everything
* Fix build issue from last commit (missed to save on VC)
* Switch BsdContext registry to a concurrent dictionary
* bsd: Implement socket creation flags logic and the non blocking flag

* Address gdkchan's comment
This fixes some regressions caused by #2971 which caused rendered 3D texture data to be lost for most slices. Fixes issues with Xenoblade 2's colour grading, probably a ton of other games.
This also removes the check from TextureCache, making it the tiniest bit smaller (any win is a win here).
* Implement IMUL shader instruction
* Implement PCNT/CONT instruction and fix FFMA32I
* Add HFMA232I to the table
* Shader cache version bump
* No Rc on Ffma32i
* Initial test for texture sync
* WIP new texture flushing setup
* Improve rules for incompatible overlaps
Fixes a lot of issues with Unreal Engine games. Still a few minor issues (some caused by dma fast path?) Needs docs and cleanup.
* Cleanup, improvements
Improve rules for fast DMA
* Small tweak to group together flushes of overlapping handles.
* Fixes, flush overlapping texture data for ASTC and BC4/5 compressed textures.
Fixes the new Life is Strange game.
* Flush overlaps before init data, fix 3d texture size/overlap stuff
* Fix 3D Textures, faster single layer flush
Note: nosy people can no longer merge this with Vulkan. (unless they are nosy enough to implement the new backend methods)
* Remove unused method
* Minor cleanup
* More cleanup
* Use the More Fun and Hopefully No Driver Bugs method for getting compressed tex too
This one's for metro
* Address feedback, ASTC+ETC to FormatClass
* Change offset to use Span slice rather than IntPtr Add
* Fix this too
* Add support for render scale to vertex stage.
Occasionally games read off textureSize on the vertex stage to inform the fragment shader what size a texture is without querying in there. Scales were not present in the vertex shader to correct the sizes, so games were providing the raw upscaled texture size to the fragment shader, which was incorrect.
One downside is that the fragment and vertex support buffer description must be identical, so the full size scales array must be defined when used. I don't think this will have an impact though. Another is that the fragment texture count must be updated when vertex shader textures are used. I'd like to correct this so that the update is folded into the update for the scales.
Also cleans up a bunch of things, like it making no sense to call CommitRenderScale for each stage.
Fixes render scale causing a weird offset bloom in Super Mario Party and Clubhouse Games. Clubhouse Games still has a pixelated look in a number of its games due to something else it does in the shader.
* Split out support buffer update, lazy updates.
* Commit support buffer before compute dispatch
* Remove unnecessary qualifier.

* ffmpeg: Add extra checks and error messages
This PR adds some checks and logging error messages related to the ffmpeg context creation, that will prevent users to open issues because they don't have the correct packages installed.
Close#2762
* Update FFmpegContext.cs
* friend: Stub IsFriendListCacheAvailable and EnsureFriendListAvailable
This PR stubs IsFriendListCacheAvailable and EnsureFriendListAvailable call of friend service which close#2896.
Sadly, Super Bomberman R Online is still stuck on the loading screen and keep calling `TryPopFromFriendInvitationStorageChannel`, probably because another issue somewhere.

This PR stub `SetMediaPlaybackStateForApplication` of the am service. Accordingly to gdkchan it's needed by the Youtube app. This is checked by RE aswell.
* kernel: Implement Thread pinning support
This commit adds support for 8.x thread pinning changes and implement SynchronizePreemptionState syscall.
Based on kernel 13.x reverse.

* kernel: fix missing critical section leave in SetActivity
Fix Unity games
* Implement missing bits on the interrupt handler and inline update pinning function as it cannot be generic
* Fix some bugs in SetActivity and SetCoreAndAffinityMask
* Address gdkchan's comments
While I'm looking to the code, I've found some syntax issue, and a little inconsistencie between `ActivateNpad` and `ActivateNpadWithRevision`. Nothing more.
* Flip scissor box when the YNegate bit is set
* Flip scissor based on screen scissor state, account for negative scissor Y
* No need for abs when we already know the value is negative
