Support PEP 698 – Override Decorator

[tmke8]

PEP 698 adds an @override decorator.

Todo:

• basic support for @override (done in Add support for PEP 698 - override decorator #14609)
• optional strict mode (relevant discussion: Provide guidance on PEP 698's strict enforcement feature of typing.override typing#1376 )

Related issue: #1888

The PEP has now been officially accepted for Python 3.12.

Ah, I shouldn't have linked this issue to the PR because there is still a missing piece: a new flag which enforces the use of @override on every overriding method ("strict mode").

[tmke8]

@hauntsaninja , can you reopen this issue? It seems I can't do that.

FYI: this discussion may be relevant for whoever implements the flag. 😄
