[issue46644] typing: remove callable() check from typing._type_check

I agree with removing this check. I suspect it's a holdover from very early typing when static types were supposed to be runtime types. Now the check is a bug magnet and doesn't serve a useful purpose.

I think we can just remove the tests that check for ints. I don't see a principled reason to special-case int literals.

I wonder if we should apply this change to 3.10 and 3.9. It's arguably a bugfix, but it's a pretty big change.
