Fortran: Unify handling of STAT= and ERRMSG= optional arguments [PR87939]

In preparing F2018 Teams handling improvements, unify handling of STAT=
and ERRMSG= optional arguments.  Handling of stat and errmsg in most
teams statements is corrected in the next patch.

Implement stat and errmsg for move_alloc () to comply with F2018.

	PR fortran/87939
