py: Make struct-initializing macros compatible with C++.

Browse Source 
This requires explicitly naming and initializing all members so add that
where needed and possible.  For MP_DEFINE_NLR_JUMP_CALLBACK_FUNCTION_1
this would require initializing the .callback member, but that's a bit
of a waste since the macro is always followed by a call to
nlr_push_jump_callback() to initialize exactly that member, so rewrite
the macro without initializers.
