blorp: update and move fast clear PIPE_CONTROLs to drivers
Before this patch, when updating the indirect clear color, BLORP only
invalidated the texture cache on gfx11. The hardware docs state that
the texture cache invalidation is also needed on gfx12 however. Add
this invalidation for gfx12 and move the fast-clear related cache
invalidations to the drivers for clarity and performance.
