Summary: The diff implements a way to use `SurfaceHandler` without using `SurfaceHandler` directly for testing and transitioning purposes. If a boolean flag is enabled all calls related to surface management will be redirected to an appropriate `SurfaceHandler` via `SurfaceManager`. Changelog: [Internal] Fabric-specific internal change.
