headline: OpenMP/Fortran fixes module-use renaming with declare mapper/reduction
tldr: The Fortran OpenMP implementation now correctly handles derived-type renaming when using `declare mapper` or `declare reduction` through module use.

The GCC Fortran front end for OpenMP has been updated to correctly account for renaming of derived types when they are used with declare mapper or declare reduction clauses through module imports. Previously, an inconsistency in type comparison logic could lead to errors. The fix aligns the comparison of types with the existing gfc_compare_derived_types function, addressing a nuance where only derived types are permitted in declare statements, but class variables can be used with mappers and reductions.
