  Log Message:
  -----------
  [flang][OpenMP] Frontend support for BEGIN/END METADIRECTIVE (#194402)

This implements parsing of BEGIN/END METADIRECTIVE, plus a minimal
semantic check for the association of a directive in a WHEN/OTHERWISE
clauses.

The same semantic checks for the context selectors apply here as in the
case of a standalone METADIRECTIVE.
