radeonsi: Implement DCC fast clear.
Uses the DCC buffer instead of the CMASK buffer. The ELIMINATE_FAST_CLEAR
still works. Furthermore, with DCC compression we can directly clear
to a limited set of colors such that we do not need a postprocessing step.
v2 Marek: check dcc_buffer && dirty_level_mask in set_sampler_view
