Automatic update from web-platform-tests
Fix SVG filter data invalidation for empty containers

Empty containers will fail to create FilterData because they have an
empty bounding box. When children were added to the container, making
the bounding box non-empty we would fail to mark the paint properties as
needing update because of the check for existing FilterData in
SVGElementResourceClient::InvalidateFilterData().

Instead always dispose of the filter data and mark paint properties for
update, and use the |filter_data_dirty_| flag as an early-out check.

Since we can now call InvalidateFilterData() directly in
SVGElementResourceClient::ResourceElementChanged(), fold
ClearFilterData() into InvalidateFilterData().
