Draft: radv: add experimental CYAN_SKILLFISH support

Enables detection of CYAN_SKILLFISH, which can be found in PS5 APU, or, more commonly, in AMD BC-250 mining board.

It is basically RDNA1/GFX10, but with added hardware ray tracing support. LLVM calls it GFX1013, see https://llvm.org/docs/AMDGPU/AMDGPUAsmGFX1013.html

This commit is not comprehensive. While some people had success with running some games on this GPU, and some non-trivial compute with ray qurey is also known to work reliably as well, there are still some issues with many other games.
