Auto merge of #24575 - marmeladema:issue-23607/compat, r=SimonSapin

Enable some mach commands to be run with python3

This change finally enable the following commands to be run with python3:
* `build`
* `test-unit`
* `package`

As previously explained, `test-tidy` will require more work in the wpt repository directly. Maybe `test-tidy --no-wpt` is achievable relatively quickly though.

For possible remaining bits that might need to be worked on, see https://github.com/servo/servo/issues/23607

<!-- 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` does not report any errors

<!-- Either: -->
- [x] There are tests for these changes

<!-- Also, please make sure that "Allow edits from maintainers" checkbox is checked, so that we can help you if you get stuck somewhere along the way.-->

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