Bug 1454591 part 1 - Generate more structured data in ServoCSSPropList.py. r=heycam This patch changes ServoCSSPropList.py to use classes for properties. This allows extending the data in the file without needing to update all users of this file. Sorting in GenerateCSSPropsGenerated.py is removed because the data file has the right order already.
