anv: remove unnecessary Tile Cache flushes

On Gfx12+, flushing tile cache ensures color/depth values are
globally visible, but that's expensive.  Most operations only
need values to be GT-visible which can be achieved with depth
or rt flush.  Remove a bunch of unnecessary Tile Cache flushes.
Fast clears and slow depth clears still require Tile Cache flush.
