Texture Sync, incompatible overlap handling, data flush improvements. (#2971)

* 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
