  [flang] Adjust semantics of the char length of an array constructor (#97337)

An implied DO loop with no trips in an array constructor does not have a
well-defined character length unless its data items have a length that
is constant expression. That works, but the implementation is too
broadly applied. An array constructor with an explicit type-spec always
has a well-defined length.
