radv: enable DCC for MSAA 2x textures on VI under an option
This can be enabled with RADV_PERFTEST=dccmsaa.
DCC for MSAA textures is actually not as easy to implement. It
looks like there is some corner cases. I will improve support
incrementally.
Vega support, as well as Polaris improvements, will be added later.
No CTS changes on Polaris using RADV_DEBUG=zerovram and
RADV_PERFTEST=dccmsaa.
