Revert "radv: disable DCC with signedness reinterpretation on GFX11"

Browse source 
This was affecting Cyberpunk and A Plague Tale Requiem but both issues
should be fixed now. The issue with A Plague Tale Requiem was because
of a game bug and vkd3d-proton now has a workaround.

This reverts commit e6735409ee.
