radv: allow fast clears for concurrent images if comp-to-single is supported

Browse Source 
Only GFX10+ is affected because older chips don't support
comp-to-single. For them, we need to implement FCE on compute with DCC
and eventually CMASK.

Fixes the gap between concurrent vs exclusive queue with Scarlet Nexus,
also gives a boost with Doom Eternal.
