glamor: Replace fallback preparation code
These offer a simpler and more efficient means for temporarily
transitioning to CPU-accessible memory for fallback implementations.
v2: Do not attempt fallbacks with GLAMOR_DRM_ONLY pixmaps
glamor cannot transfer pixels for GLAMOR_DRM_ONLY pixmaps using
glReadPixels and glTexSubImage2D, and so there's no way to perform
fallback operations with these pixmaps.
