Servo changes for bug 1347409

bug 1347409 is introducing a fallback type for SVG paint servers so that we can distinguish between url(something) and url(something) none and serialise those cases correctly. When we get a url(something) color we need to set the mFallbackType to eStyleSVGFallbackType_Color.

This change has already been reviewed in https://bugzilla.mozilla.org/show_bug.cgi?id=1347409

<!-- 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
- [X] These changes do not require tests because they are covered by tests that will land in gecko as part of the rest of the patch there.

<!-- 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. -->
