servo: Merge #11267 - Add --all option to mach test-tidy, with compatibility with --faster (from mitchhentges:test-tidy-sanic-by-default); r=aneeshusa

Thank you for contributing to Servo! Please replace each `[ ]` by `[X]` when the step is complete, and replace `__` with appropriate data:
- [x] `./mach build -d` does not report any errors
- [x] `./mach test-tidy --faster` does not report any errors
- [X] These changes partially fix #11217

Either:
- [ ] There are tests for these changes OR
- [X] These changes do not require tests because it just affects `mach` script parameters

Pull requests that do not address these steps are welcome, but they will require additional verification as part of the review process.
