intel/cs: Grow prog_data::param on-demand for thread_local_id_index

Instead of making the caller of brw_compile_cs add something to the
param array for thread_local_id_index, just add it on-demand in
brw_nir_intrinsics and grow the array.  This is now safe to do because
everyone is now using ralloc for prog_data::param.
