Draft: turnip: VK_EXT_device_generated_commands

Connor Abbott requested to merge cwabbott0/mesa:review/tu-dgc into main

This includes full support, including graphics "indirect execution sets" which allow the user to switch shaders in the middle of a sequence of indirectly generated commands. We also add support to cffdump/crashdec to be able to decode the generated commands, which was invaluable during bringup. Things still to be done:

  • Either support the pre-a750 method of uploading consts using CP_LOAD_STATE, or make all a7xx use the new method of using a UBO.
  • Rerun the rest of CTS to make sure I didn't break anything.
  • More testing with vkd3d-proton once support lands there.

Similarly to !28447, this depends on !27776 (merged) to enable shaderInt64 and avoid capability spam from the preprocess compute shader.
