Remove include of StyleResolverState.h from StyleResolver.h

Instead add includes to .cpp files that needs things that
StyleResolverState.h included for them.

This brings down the amount of recompilation drastically (from 
~720 to ~20) when touching files like FontBuilder.h or
StyleResolverState.h.
