Charlie Marsh f1db842821 [ty] Avoid panic for comparison on synthesized variants (#22509) ...

## Summary

Like `ProtocolInstance`, we now use `left.cmp(right)` by deriving
`PartialOrd` and `Ord`. IIUC, this uses Salsa ID for Salsa-interned
types, but avoids `None.cmp(None)` for synthesized variants.

Closes https://github.com/astral-sh/ty/issues/2451.
