tldr: The OpenMP ALLOCATE directive can no longer be used with omp_mem_alloc allocators for static variables, aligning with OpenMP 6.1.

The OpenMP specification is evolving to disallow the use of omp_{cgroup,pteam,thread}_mem_alloc allocators for static variables in the ALLOCATE directive. This commit enforces this restriction in GCC for both Fortran and C, rejecting such usage during compilation. This change aligns GCC’s behavior with the upcoming OpenMP 6.1 specification and the existing restrictions in OpenMP 6.0.
