David Peter 5dd56264fb [ty] Add tests for generic implicit type aliases (#21522) ...

## Summary

Add a set of comprehensive tests for generic implicit type aliases to
illustrate the current behavior with many flavors of `@Todo` types and
false positive diagnostics.

The tests are partially based on the typing conformance suite, and the
expected behavior has been checked against other type checkers.
