intel/nir: Move lower_mem_access_bit_sizes to postprocess_nir

It doesn't really matter where this pass goes as long as it's after we
call nir_lower_explicit_io and before we go into the back-end.  Putting
it brw_postprocess_nir lets us move nir_lower_explicit_io significantly
later in the pipeline.
