radv: move userdata sgpr ownership to compiler side.
This isn't fully what we want yet, but is a good step on the way.
This allows the compiler to create the information structures
for the state setting side, however the state setting still expects
things to be pretty much in 2 sgpr wide register sets, and can't
handle the indirect setting yet.
