V3DV Vulkan 1.2 status

A quick update on my latest activities around V3DV: I’ve been focusing on getting the driver ready for Vulkan 1.2 conformance, which mostly involved fixing a few CTS tests of the kind that would only fail occasionally, these are always fun :). I think we have fixed all the issues now and we are ready to submit conformance to Khronos, my colleague Alejandro PiƱeiro is now working on that.
