Cleanup StyleRareInheritedData.

This patch changes StyleRareInheritedData to make it easier to generate:
- Remove unused destructor
- Replace explicit copy constructor with RefCountedCopyable
- Replace forward declarations with #includes.

This is in preparation for generating StyleRareInheritedData. While this
patch may increase compile times, we would have to pay this cost anyway
when we generate StyleRareInheritedData in ComputedStyleBase.
