  [GPU Process] [Filters] Cache the SVGFilter applying results in RemoteResourceCache

Reviewed by Simon Fraser.

This allows caching the results of applying an SVGFilter to a source ImageBuffer
in GPU Process. We should be able to use the cached result if the Filter was not
changed. We should be also able to clear some of the result FilterImages if a
FilterEffect was changed.
