Do models.Model adjustments from get_metaclass_hook

[flaeppe]

The called hook expects/wants the class body analyzed, but the get_customize_class_mro_hook hook, that it was previously called from, invokes the hook before the class body has been analyzed..

Docs: https://mypy.readthedocs.io/en/stable/extending_mypy.html#current-list-of-plugin-hooks

get_customize_class_mro_hook() can be used to modify class MRO (for example insert some entries there) before the class body is analyzed.

Thanks! I think that we didn't have this hook back in the days of the original code.
