radv: disable DCC for DOOM 2016 and Wolfenstein II

Both games perform two image layout transitions with the same image
in the same pipeline barrier with UNDEFINED and this re-initializes
DCC to the uncompressed state. No ideal solution sadly. Note that
both games declare all images as CONCURRENT.

This fixes rendering issues on GFX10+ because DCC for stores is
supported and this implicitly enables DCC for concurrent.
