  [flang] Refine handling of NULL() actual to non-optional allocatable … (#116126)

…dummy

We presently allow a NULL() actual argument to associate with a
non-optional dummy allocatable argument only under INTENT(IN). This is
too strict, as it precludes the case of a dummy argument with default
intent. Continue to require that the actual argument be definable under
INTENT(OUT) and INTENT(IN OUT), and (contra XLF) interpret NULL() as
being an expression, not a definable variable, even when it is given an
allocatable MOLD.
