[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
https://github.com/sphinx-doc/sphinx/blob/2b7e3adf27c158305acca9b5e4d0d93d3e4c6f09/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.
