WIP: Virgl add tweak interface
Enable the use of virgl (drm) and add tweaks for BRGA-sRGB blits, render targets, and transform feedback 3 emulation.
The two BGRA_SRGB tweaks are needed to correctly render Half-Life 2 (blit) and The Raven Remastered (render target).
The host side is here: virgl/virglrenderer!207 (closed)
