Forward declare StyleVariableData in StyleRareInheritedData instead of including it

This patch replaces an include of StyleVariableData with a forward
declaration in StyleRareInheritedData. This significantly reduces the
number of files that need to recompile when touching files like
CSSVariableData and CSSParserToken from ~900 to ~50.
