Reduce amount of rebuilding when touching networking headers

        This uses a number of common unsurprising techniques. One interesting observation
        is that including CachedResource related headers is very expensive. We can usually
        get away with their Client counterparts, and with CachedResourceHandle.

        * page/Frame.cpp:
        * page/Frame.h:
        Don't include FrameLoader, greatly reducing include graph for most non-loader files.
        This required making Frame::init() non-inline - I'm not sure why it ever was.

        * loader/FrameLoader.cpp:
        * loader/FrameLoader.h:
        Even though FrameLoader is logically on loading side of WebCore, it's included in
        too many places. Not including PolicyChecker.h and ResourceHandle.h was among the
        largest wins. As a future improvement, we should probably convert other members
        to OwnPtrs.

        * css/CSSCrossfadeValue.h: Initializing CachedResourceHandle with 0 requires a
        definition of a class it holds, but default construction does not.

        * loader/CrossOriginAccessControl.h: This file among others only needs ResourceHandleTypes.h,
        not ResourceHandle.h. This header is semi-recent, so not all include sites were updated.

        * loader/cache/CachedFont.h:
        * loader/cache/CachedFontClient.h: Added.
        * loader/cache/CachedRawResource.h:
        * loader/cache/CachedRawResourceClient.h: Added.
        * loader/cache/CachedSVGDocument.h:
        * loader/cache/CachedSVGDocumentClient.h: Added.
        These types were defining client types in the same headers, making it impossible
        to avoid including networking headers through CachedResource. Moved clients into
        separate files.

        * plugins/PluginStream.h:
        * plugins/PluginStreamClient.h: Added.
        Similar situation here.

        * loader/cache/CachedResourceHandle.cpp:
        * loader/cache/CachedResourceHandle.h:
        Moved functions that need to know about CachedResource to .cpp file. This is another
        huge win. Added a destructor, so that CachedResource woudn't be needed in all files
        that include CachedResourceHandle.

        * loader/cache/CachedSVGDocumentReference.cpp: Added.
        * loader/cache/CachedSVGDocumentReference.h:
        Moved constructor and virtual function implementations to a .cpp file - they need
        not inlining, and this lets us avoid including CachedSVGDocument.h in the header.

        * platform/graphics/filters/FilterOperation.cpp:
        * platform/graphics/filters/FilterOperation.h:
        Avoid including CachedSVGDocumentReference.h. This is not such a big win now that
        CachedSVGDocumentReference.h itself is smaller, but FilterOperation is so clearly
        rendering code that it seems best to cut any ties with resources and loading.
        Added a virtual destrutor in .cpp file, because inline destructors in polymorphic
        classes are generally harmful (due to code bloat).

        * plugins/PluginRequest.h: Added.
        * plugins/PluginView.h:
        Moved PluginRequest into a separate file, it was out of place in a view hierarchy
        class file.

        * rendering/RenderImageResource.cpp:
        * rendering/RenderImageResource.h:
        Moved definitions of virtual functions to a .cpp file. Thre is no win from having
        them inline, and now we don't need CachedImage.h in the header.

        * rendering/style/StyleCustomFilterProgram.cpp: Added.
        * rendering/style/StyleCustomFilterProgram.h:
        Ditto.

Remove unused member variable m_useLatchedEventNode from PlatformWheelEvent.h
https://bugs.webkit.org/show_bug.cgi?id=107314

Reviewed by Darin Adler.

EventHandler::handleGestureScrollCore() was removed in http://trac.webkit.org/changeset/140177,
and this was the only place where the member variable |m_useLatchedEventNode| in
PlatformWheelEvent was mutated. This variable is no longer needed and so it should be removed.

No change in behavior, so no new tests needed.
