gdb: add type::is_prototyped / type::set_is_prototyped

Add the `is_prototyped` and `set_is_prototyped` methods on `struct
type`, in order to remove the `TYPE_PROTOTYPED` macro.  In this patch,
the macro is changed to use the getter, so all the call sites of the
macro that are used as a setter are changed to use the setter method
directly.  The next patch will remove the macro completely.

gdb/ChangeLog:

	* gdbtypes.h (struct type) <is_prototyped, set_is_prototyped>:
	New methods.
	(TYPE_PROTOTYPED): Use type::is_prototyped, change all write
	call sites to use type::set_is_prototyped.
