[ty] Match variadic argument to variadic parameter (#20511) 
## Summary

Closes: https://github.com/astral-sh/ty/issues/1236

This PR fixes a bug where the variadic argument wouldn't match against
the variadic parameter in certain scenarios.

This was happening because I didn't realize that the `all_elements`
iterator wouldn't keep on returning the variable element (which is
correct, I just didn't realize it back then).

I don't think we can use the `resize` method here because we don't know
how many parameters this variadic argument is matching against as this
is where the actual parameter matching occurs.

## Test Plan

Expand test cases to consider a few more combinations of arguments and
parameters which are variadic.
