[ty] linear variance inference for PEP-695 type parameters (#18713) 
## Summary

Implement linear-time variance inference for type variables
(https://github.com/astral-sh/ty/issues/488).

Inspired by Martin Huschenbett's [PyCon 2025
Talk](https://www.youtube.com/watch?v=7uixlNTOY4s&t=9705s).

## Test Plan

update tests, add new tests, including for mutually recursive classes
