Refactor auto-sync updater
This refactors the auto-sync updater scripts, adds multiple tests and some other smaller things:
- Converts the updater in a proper Python package.
- Renaming was done to fit this new package structure.
- Format code with usort and black and enforce it with the CI.
- Add license information to auto-sync scripts.
- Update tree-sitter-cpp to v20.0.5
- Fix py-tree-sitter version to `< 0.22.0` due to https://github.com/tree-sitter/tree-sitter-cpp/issues/250
- Allow file/dir creation of non existing paths.
- Add CI tests for Patch, inc gen, translation and diff persistence testing.
- Implement editing of diffs with an editor.
- Fix: Add Namespace id also to anonymous enumeration members.
