ea87d7c0 - [flang] Add control and a portability warning for an extension (#137995)

[flang] Add control and a portability warning for an extension (#137995) This compiler allows an element of an assumed-shape array or POINTER to be used in sequence association as an actual argument, so long as the array is declared to have the CONTIGUOUS attribute. Make sure that this extension is under control of a LanguageFeature enum, so that a hypothetical compiler driver option could disable it, and add an optional portability warning for its use.
