Refactor local lint (#58798)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/58798
In #58623 there was a bug in `make quicklint` where ShellCheck would run on the entire repo when there were no files. This PR fixes that by refactoring out common stuff (like skipping quicklint when there are no files, let checks do their own file filtering) and pushes the logic into a runner class.
