py/objdict: Make mp_obj_dict_get_map an inline function.

It's a very simple function and saves code, and improves efficiency, by
being inline.  Note that this is an auxiliary helper function and so
doesn't need mp_check_self -- that's used for functions that can be
accessed directly from Python code (eg from a method table).
