The StyleRule classes supported copy() operations and mutable property sets so that we could do copy-on-write and mutate them using the CSSOM. Sky doesn't have a CSSOM like this though, so we can remove all this code and make the StyleRule classes effectively immutable after construction (the parser does mutate some rules though). I also removed some other dead code in the StyleRule hierarchy, like some left over mutation methods that the CSSOM used to use.
