py/emitglue: Introduce mp_proto_fun_t as a more general mp_raw_code_t.

Browse Source 
Allows bytecode itself to be used instead of an mp_raw_code_t in the simple
and common cases of a bytecode function without any children.

This can be used to further reduce frozen code size, and has the potential
to optimise other areas like importing.
