re PR fortran/36031 (ARM -fshort-enums attribute not emitted for Fortran)

	PR fortran/36031

	* decl.c (set_enum_kind): Use global short-enums flag.
	* gfortran.h (gfc_option_t): Remove short_enums flag.
	* lang.opt (-fshort-enums): Refer to C documentation.
	* options.c (gfc_init_options, gfc_handle_option): Use global
	short-enums flag.
