Alex Waygood 989075dc16 [red-knot] Add tests asserting that KnownClass::to_instance() doesn't unexpectedly fallback to Type::Unknown with full typeshed stubs (#16608 )

## Summary

One of the motivations in https://github.com/astral-sh/ruff/pull/16428
for panicking when the `test` or `debug_assertions` features are enabled
and a lookup of a `KnownClass` fails is that we've had some latent bugs
in our code where certain variants have been silently falling back to
`Unknown` in every typeshed lookup without us realising. But that in
itself isn't a great motivation for panicking in
`KnownClass::to_instance()`, since we can fairly easily add some tests
that assert that we don't unexpectedly fallback to `Unknown` for any
`KnownClass` variant. This PR adds those tests.

## Test Plan

`cargo test -p red_knot_python_semantic`
