nir/opcodes: Remove the per_component info field



Originally, this field was intended for determining if the given
instruction acted per-component or if it had mismatching source and
destination sizes that would have to be interpreted specially.  However, we
can easily derive this from output_size == 0, so it's not really that
useful.  Also, the values we were setting in nir_opcodes.h for this field
were completely bogus and it was never used.
