milescovielloandClaude Opus 5.5 51d6c2f9f2 feat(agc): take RADV's comp-to-single clear of a multisampled DCC target
RADV clears a multisampled DCC target to a color other than 0000, 0001,
1110 or 1111 with radv_clear_dcc_comp_to_single: a compute dispatch stores
the color at the first pixel of every DCC block through a uint storage view,
and the DCC keys become 0x10. The driver refused that view of a resident
target, made a separate target in the view's format otherwise, and couldn't
import 0x10 keys.

The dispatch is now recognized by its code and not run. Its clear color is
recorded for the surface its image descriptor names, and 0x10 keys on a
multisampled target of that surface, size and sample count import as a clear
to that color, for texels up to 32 bits.
