bugfix [#23182] Using self.report() inside poll() gives crash

poll() function is now a static method in python, this is more correct, matching C where the operator is not created to run poll.


    def poll(self, context): ...

is now...

    @staticmethod
    def poll(context): ...

Pythons way of doing static methods is a bit odd but cant be helped :|

This does make subclassing poll functions with COMPAT_ENGINES break, so had to modify quite a few scripts for this.
