Auto merge of #15356 - servo:font-face-descriptors, r=Manishearth
Add support for more @font-face descriptors <!-- Please describe your changes on the following line: --> Part of https://bugzilla.mozilla.org/show_bug.cgi?id=1290237. I’ll add conversions to `nsCSSValue` separately because that requires new C++ functions in the stylo repository. r? @bholley --- <!-- 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 - [ ] These changes fix #__ (github issue number if applicable). <!-- Either: --> - [ ] There are tests for these changes OR - [ ] These changes do not require tests because _____ <!-- Pull requests that do not address these steps are welcome, but they will require additional verification as part of the review process. --> <!-- Reviewable:start --> --- This change is [<img src="https://reviewable.io/review_button.svg" height="34" align="absmiddle" alt="Reviewable"/>](https://reviewable.io/reviews/servo/servo/15356) <!-- Reviewable:end -->
