radv: On GFX11, use box sorting heuristic based on ray flags
...
Use box with largest ray interval for shadow rays (terminate on first
hit) as it maximizes the probability of finding some object in that box;
for reflection (closest hit) rays, use midpoint instead, which defers
processing of larger boxes the ray origin is in in favor of smaller
boxes closer to origin.
Since the sorting mode must be uniform, when terminate_on_first_hit flag
is divergent, we leave it as closest.

...
this allows amd drivers to disable llvm support while still allowing
llvmpipe/lavapipe to be built
by disabling llvm support in amd drivers, the load times for these drivers
decreases by 5-10ms

radv/rra: Dump basic ray history tokens

This only dumps the begin tokens. Tokens are written to a buffer
containing a 12 byte header at the beginning.
We use an intermediate format for the ray history tokens because the RRA
format is very inefficient.
