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

Removed unnecessary pub modifiers from DOM class functions get_instance_id.

<!-- 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 there are no WebBluetooth test API implementation yet.

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