Damien George bfbd94401d py: Make mp_obj_get_type() return a const ptr to mp_obj_type_t.
Most types are in rodata/ROM, and mp_obj_base_t.type is a constant pointer,
so enforce this const-ness throughout the code base.  If a type ever needs
to be modified (eg a user type) then a simple cast can be used.
