Fortran: optional argument DIM for intrinsics NORM2, PARITY must be scalar

gcc/fortran/ChangeLog:

	PR fortran/104212
	* check.cc (gfc_check_norm2): Check that optional argument DIM is
	scalar.
	(gfc_check_parity): Likewise.

gcc/testsuite/ChangeLog:

	PR fortran/104212
	* gfortran.dg/argument_checking_26.f90: New test.
