intel/fs: fix metadata preserve on trace_ray intrinsic

Browse Source 
c78be5da30 ("intel/fs: lower ray query intrinsics") introduced a
helper function using nir_(push|pop)_if which invalidated dominance &
block_index for the replacement of nir_intrinsic_rt_trace_ray.

We can still keep dominance/block_index metadata for the lowering of
nir_intrinsic_rt_execute_callable though.

This change uses 2 different lowering function with correct metadata
preservation.
