radv: implement compressed FMASK texture reads with RADV_PERFTEST=tccompatcmask
This allows us to disable the FMASK decompress pass when
transitioning from CB writes to shader reads.
This will likely be improved and enabled by default in the future.
No CTS regressions on GFX8 but a few number of multisample CTS
failures on GFX9 (they look related to the small hint).
