radv/clear: add r32g32b32a32 fast clear support (v2)

Browse source 
We can only fast clear 128-bit images if the r/g/b channels
are the same, and we are using DCC.

For DCC we'll bail out on translate if this isn't true,
and we catch cmask clears explicitly.

v2: remove 64-bit block (Bas), add uint32 as well.
