servo: Merge #14312 - Implement discarding Document objects to reclaim space (from asajeffrey:script-discard-documents); r=cbrewster
<!-- Please describe your changes on the following line: -->
This PR implements document discarding. Active documents are kept alive strongly, but inactive documents are only kept alive weakly. When a document is GCd, it is marked as discarded, and if it is every reactivated, a reload of the URL is triggered.
Note that this PR is pretty aggressive about discarding, and can any inactive document (other than those being kept alive by other same-origin pipelines). We might want to damp it down a bit.
Also note that this interacts with browser.html in that the reloading triggered by reactivating a document triggers mozbrowser events.
To test this, I added a `-Zdiscard-inactive-documents` debug flag, which discards all inactive documents, even ones which are reachable through other same-origin pipelines.

<!-- 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 fix #14262.
- [X] These changes do not require tests because we should be able to use the existing tests with `-Zdiscard-inactive-documents`.
<!-- Pull requests that do not address these steps are welcome, but they will require additional verification as part of the review process. -->
