Move implementation of WebFilterOperations into cc

This moves the implementation of WebFilterOperations into cc, and
(behind an #ifdef) defines a WebFilterOperationsImpl class that
implements the WebFilterOperations interface by wrapping a 
cc::FilterOperations.

With this change, cc and ui/compositor no longer need to include
WebFilterOperations.h.
