[ty] Support single-starred argument for overload call (#20223)
## Summary

closes: https://github.com/astral-sh/ty/issues/247

This PR adds support for variadic arguments to overload call evaluation.

This basically boils down to making sure that the overloads are not
filtered out incorrectly during the step 5 in the overload call
evaluation algorithm. For context, the step 5 tries to filter out the
remaining overloads after finding an overload where the materialization
of argument types are assignable to the parameter types.

The issue with the previous implementation was that it wouldn't unpack
the variadic argument and wouldn't consider the many-to-one (multiple
arguments mapping to a single variadic parameter) correctly. This PR
fixes that.

## Test Plan

Update existing test cases and resolve the TODOs.
