Summary

Fixes astral-sh/ty#1867. In certain cases where a function definition has not yet been completed, we can end up associating overloads from a totally different function (in a totally different file) with the unfinished function in the file being checked. That then leads us to panic in other places that assume (reasonably) that a function's overloads will all always be defined in a single file.

This PR fixes the panic by adding more sanity checks to OverloadLiteral::previous_overload().

Test Plan

Added a regression test that causes us to panic on main.
