dwarf: externalize lookup_type_die

Expose the function lookup_type_die in dwarf2out, so that it can be used
by CTF/BTF when adding BPF CO-RE information. The function is now
non-static, and an extern prototype is added in dwarf2out.h.

gcc/ChangeLog:

	* dwarf2out.c (lookup_type_die): Function is no longer static.
	* dwarf2out.h: Expose it here.
