Fortran: Update use_device_ptr for OpenMP 5.1 [PR105318]

Fortran: Update use_device_ptr for OpenMP 5.1 [PR105318]

OpenMP 5.1 added has_device_addr and relaxed the restrictions for
use_device_ptr, including processing non-type(c_ptr) arguments as
if has_device_addr was used. (There is a semantic difference.)

For completeness, the likewise change was done for 'use_device_ptr',
where non-type(c_ptr) arguments now use use_device_addr.

Finally, a warning for 'device(omp_{initial,invalid}_device)' was
silenced on the way as affecting the new testcase.

	PR fortran/105318

gcc/fortran/ChangeLog:
	* openmp.cc (resolve_omp_clauses): Update is_device_ptr restrictions
	for OpenMP 5.1 and map to has_device_addr where applicable; map
	use_device_ptr to use_device_addr where applicable.
	Silence integer-range warning for device(omp_{initial,invalid}_device).
