Retain extra ellipses in protocols and abstract methods

[charliermarsh]

Summary

It turns out that some type checkers rely on the presence of ellipses in Protocol interfaces and abstract methods, in order to differentiate between default implementations and stubs. This PR modifies the preview behavior of PIE790 to avoid flagging "unnecessary" ellipses in such cases.

Closes #8756.
