v3dv: fix depth/stencil clears on hardware

There is a hw bug by which the only way to clear the depth/stencil
tile buffers is to emit a clear of all tile buffers, so if we have
to do any such clears, we just emit a single clear of all tile
buffers and skip doing any per-buffer clears, even for color buffers,
since they would be redundant.
