[ty] Argument type expansion for overload call evaluation (#18382) 
## Summary

Part of astral-sh/ty#104, closes: astral-sh/ty#468

This PR implements the argument type expansion which is step 3 of the
overload call evaluation algorithm.

Specifically, this step needs to be taken if type checking resolves to
no matching overload and there are argument types that can be expanded.

## Test Plan

Add new test cases.

## Ecosystem analysis

This PR removes 174 `no-matching-overload` false positives -- I looked
at a lot of them and they all are false positives.

One thing that I'm not able to understand is that in
2b7e3adf27/sphinx/ext/autodoc/preserve_defaults.py (L179)
the inferred type of `value` is `str | None` by ty and Pyright, which is
correct, but it's only ty that raises `invalid-argument-type` error
while Pyright doesn't. The constructor method of `DefaultValue` has
declared type of `str` which is invalid.

There are few cases of false positives resulting due to the fact that ty
doesn't implement narrowing on attribute expressions.
