Use pre-commit for CI style checks. (#3062)

This PR adopts `pre-commit` in CI style checks and updates a few of the hooks (flake8, clang-format, and the copyright checker).

This helps with the ongoing transition to GitHub Actions by centralizing style checks.

I also applied a significant set of changes from `clang-format` and `flake8` suggestions in commits cfe6395 and adf0741. To minimize the diff in this PR, we can split those two commits into their own PRs with some small tweaks to the `pre-commit` configuration. Let me know if you'd like me to do this.
