[ty] The runtime object typing.Protocol is an instance of _ProtocolMeta (#20488) 
## Summary

Fixes https://github.com/astral-sh/ty/issues/1218.

This bug doesn't currently cause us any real-world issues, because we
don't yet understand the signatures typeshed gives us for `isinstance()`
and `issubclass()` (typeshed's annotations there use PEP-613 type
aliases). #20107 demonstrates that this will start causing us issues as
soon as we add support for PEP-613 aliases, however, so it makes sense
to fix it now.
