Vulkan: Buffer Mirrors for MacOS performance (#4899)1.1.988
* Initial implementation of buffer mirrors
Generally slower right now, goal is to reduce render passes in games that do inline updates
Fix support buffer mirrors
Reintroduce vertex buffer mirror
Add storage buffer support
Optimisation part 1
More optimisation
Avoid useless data copies.
Remove unused cbIndex stuff
Properly set write flag for storage buffers.
Fix minor issues
Not sure why this was here.
Fix BufferRangeList
Fix some big issues
Align storage buffers rather than getting full buffer as a range
Improves mirrorability of read-only storage buffers
Increase staging buffer size, as it now contains mirrors
Fix some issues with buffers not updating
Fix buffer SetDataUnchecked offset for one of the paths when using mirrors
Fix buffer mirrors interaction with buffer textures
Fix mirror rebinding
Move GetBuffer calls on indirect draws before BeginRenderPass to avoid draws without render pass
Fix mirrors rebase
Fix rebase 2023
* Fix crash when using stale vertex buffer
Similar to `Get` with a size that's too large, just treat it as a clamp.
* Explicitly set support buffer as mirrorable
* Address feedback
* Remove unused fragment of MVK workaround
* Replace logging for staging buffer OOM
* Address format issues
* Address more format issues
* Mini cleanup
* Address more things
* Rename BufferRangeList
* Support bounding range for ClearMirrors and UploadPendingData
* Add maximum size for vertex buffer mirrors
* Enable index buffer mirrors
Enabled on all platforms for the IbStreamer.
* Feedback
* Remove mystery BufferCache change
Probably macos related?
* Fix mirrors not creating when staging buffer is empty.
* Change log level to debug
