re PR fortran/45308 ([F2003] DATE_AND_TIME does _not_ blank-pad strings)

	PR fortran/45308
	* intrinsics/date_and_time.c (date_and_time): Pass __{zone,time,date}_len
	instead of {ZONE,TIME,DATE}_LEN as second argument to fstrcpy.  Drop
	asserts.  Adjust comment to the F2003 wording from the F95 wording.

	* gfortran.dg/pr45308.f03: New test.
