Dhruv Manilawala 0cbe2af18b [ty] Add basic support for overloads in ParamSpec (#21946) ...

## Summary

fixes: https://github.com/astral-sh/ty/issues/1838

This PR adds basic support for overloaded function when used to
specialize a `ParamSpec` type variable.

Following cases are still remaining:
1. Updating the specialization with the matching overload after the
paramspec sub-call logic
2. Updating the specialization with the matching overload using the
return type

Both of these cases are present in the mdtest file.

## Test Plan

Update mdtest with new cases.
