nir: add variant of lower_io_to_scalar to be called earlier

This is intended to be called before nir_lower_io() so that we
can do some linking optimisations with the results. It can also
be used with drivers that don't use nir_lower_io() at all such
as RADV.

v2: pass mode mask rather than first and last stage integer.
