Minor clean-up after r81156, r81172

Follow-up for:
<http://webkit.org/b/56381> Objective-C classes should be typedef-ed as structs (not void*) in C++

* platform/graphics/GraphicsLayer.h: Removed unused @class
WebLayer declaration.
* platform/graphics/ca/PlatformCAAnimation.h: Changed typedef
struct CAPropertyAnimation to class declaration.
