[Filters] Manage applying the CSSFilter using FilterTargetSwitcher
https://bugs.webkit.org/show_bug.cgi?id=248175
rdar://102585518
Reviewed by Simon Fraser.
FilterTargetSwitcher can prepare the drawing context and can apply the filter
when
the source image drawing is complete. So it will make since if we unify applying
the CSSFilter, SVGFilter and canvas filter by using this class.
This patch will use FilterTargetSwitcher to apply the CSSFilter. In future
patches
SVGFilter and canvas filter will use it as well.
For applying software filters we will use a variant of FilterTargetSwitcher
named
FilterImageTargetSwitcher. This class will manage creating the source image and
maintaining the filter results. A new super class of FilterTargetSwitcher will
be
introduced in future patches for the CoreGraphics filters.
