Auto merge of #16845 - asajeffrey:script-rename-browsing-contexts, r=jdm

Renamed BrowsingContext to WindowProxy in script.

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

Renamed `script::dom::BrowsingContext` to `script::dom::WindowProxy`.

The browsing context is mostly maintained in the constellation, not in script. It would be nice to rename `constellation::Frame` to `constellation::BrowsingContext`, but that will be very confusing if there are two `BrowsingContext` types.

<!-- 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 renamings aren't externally visible

<!-- 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. -->
