  Log Message:
  -----------
  [Flang][OpenMP] Add support for interop construct (#203959)

This adds support for the OpenMP interop construct, which enables
interoperability with foreign runtime environments (e.g., CUDA, HIP).
The init, use, and destroy action clauses are lowered from the Fortran
parse tree to MLIR interop ops and translated to the appropriate runtime
calls. The omp_lib module is extended with interop query API interfaces,
property constants, and return code constants. A semantics fix relaxes
the depend/targetsync constraint for use/destroy directives where the
interop type was established at a separate init site. Unsupported depend
clauses and prefer_type selector-list forms emit explicit diagnostics
instead of being silently dropped.
