servo: Merge #20177 - removed default_data_dir() and default_cache_dir() (from petre2dor:removeUnusedCode); r=jdm

<!-- Please describe your changes on the following line: -->

I removed `default_data_dir()` and `default_cache_dir()` from `components/config/basedir.rs` because they were never called.

<!-- 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
- [x] These changes do not require tests because they only remove untested code

<!-- 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. -->
