Get rid of VEC(interp_factory_p)

Replace it with an std::vector.

gdb/ChangeLog:

	* interps.c (struct interp_factory): Add constructor.
	(interp_factory_p): Remove typedef.
	(DEF_VEC_P(interp_factory_p)): Remove.
	(interpreter_factories): Change type to std::vector.
	(interp_factory_register): Adjust.
	(interp_lookup): Adjust.
	(interpreter_completer): Adjust.
