WebBluetooth fixes for the wpt tests

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

Note: depends on #13612
WebBluetooth fixes for the failing wpt tests, excluding the `disconnect-during` tests cases, due to the lack of the event handling in the current implementation.

- [x] `./mach build -d` does not report any errors
- [x] `./mach test-tidy` does not report any errors
- [x] There are tests for these changes OR

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