drm/amdgpu: optionally do a writeback but don't invalidate TC for IB fences
There is a new IB flag that enables this new behavior.
Full invalidation is unnecessary for RELEASE_MEM and doesn't make sense
when draw calls from two adjacent gfx IBs run in parallel. This will be
the new default for Mesa.
v2: bump the version
