Sam Estep 737d920b21 Strictly type everything in .github and tools (#59117)
Summary:
This PR greatly simplifies `mypy-strict.ini` by strictly typing everything in `.github` and `tools`, rather than picking and choosing only specific files in those two dirs. It also removes `warn_unused_ignores` from `mypy-strict.ini`, for reasons described in https://github.com/pytorch/pytorch/pull/56402#issuecomment-822743795: basically, that setting makes life more difficult depending on what libraries you have installed locally vs in CI (e.g. `ruamel`).

Pull Request resolved: https://github.com/pytorch/pytorch/pull/59117

Test Plan:
```
flake8
mypy --config mypy-strict.ini
```
