gccrs: libproc_macro: Add named constructor

Add named constructor directly in Ident struct.

libgrust/ChangeLog:

	* libproc_macro/ident.cc (Ident__new): Use named
	constructor.
	(Ident__new_raw): Use named constructor.
	(Ident__clone): Use clone member function.
	(Ident::clone): Make clone const.
	(Ident::make_ident): Add named construcot.
	* libproc_macro/ident.h (struct Ident): Add named
	constructor prototypes.
