radv: advertise VK_KHR_unified_image_layouts on GFX11+

Browse Source 
On GFX12, everything is compressed with DCC and it's completely
transparent to the userspace driver.

On GFX11-GFX11.5, DCC can compress everything with GENERAL and FMASK
has been merged with DCC.

On GFX10-GFX10.3, MSAA through FMASK can't be compressed with GENERAL
and this will hurt performance.

On GFX6-9, DCC can't be supported with GENERAL because no DCC stores,
so this will destroy performance.
