servo: Merge #12572 - 10933/shorthands (from craftytrickster:10933/shorthands); r=emilio 

<!-- Please describe your changes on the following line: -->
This implements the serialization of nearly all of the css shorthand properties with the following exceptions:

1. font - this may be implemented correctly, but I am not 100% sure
2. border-radius - I do not know how to implement this, since I am not familiar with how the property works
3. background - this is implemented, but I think that the implementation might be a tiny bit off.

---
<!-- 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 #10933  (github issue number if applicable). Also fixes issue #11448

<!-- Either: -->
- [X] 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. -->
