The major differences compared to the NV extensions are:
- support for the sequence index as push constants
- support for draw with count tokens (note that DrawID is zero for
normal draws)
- support for raytracing
- support for IES (only compute is supported for now)
- improved preprocessing support with the state command buffer param
The NV DGC extensions were only enabled for vkd3d-proton and it will
maintain both paths for a while, so they can be replaced by the EXT.
