Need compare between metaclass and internal contents of classcell in __build_class__ #3865

Feature

https://github.com/RustPython/RustPython/blob/main/vm/src/stdlib/builtins.rs#L899-L919
We should compare between class (invoked by metaclass) and classcell's internal contents before exiting __build_class__
At now we manually set classcell's internal contents with class, but this should be done in type.__new__
