nir/builder: Add a nir_extract_bits helper

This new helper is better than nir_bitcast_vector because it's able to
take a (mostly) arbitrary range from the source vector.  The only
requirement is that first_bit has to be aligned to the smaller of the
two bit sizes.  It wouldn't be hard to lift that requirement but it's
reasonable for now.
