Charlie Marsh 385dd2770b [ty] Avoid double-inference on non-tuple argument to Annotated (#21837) ...

## Summary

If you pass a non-tuple to `Annotated`, we end up running inference on
it twice. I _think_ the only case here is `Annotated[]`, where we insert
a (fake) empty `Name` node in the slice.

Closes https://github.com/astral-sh/ty/issues/1801.
