servo: Merge #11972 - Staticize CASCADE_PROPERTIES, (temporarily) fix stylo path for animations, and introduce the long-term path to follow (from emilio:style-thingies); r=bholley
<!-- Please describe your changes on the following line: --> --- <!-- 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 <!-- Either: --> - [x] These changes do not require tests because refactoring + geckolib <!-- Pull requests that do not address these steps are welcome, but they will require additional verification as part of the review process. --> @bholley: I was going to do this "the good way", but that involves quite a few properties, so I thought I'd rather unlock stylo before :) r? @bholley Source-Repo: https://github.com/servo/servo Source-Revision: a77cc9950fb13ccd674a10e46c2327bfa0735dab
