This will make it easier to test CellLayout, also we should avoid circular dependencies as much as poisble. This also allows the CellLayout to be created in other containers that are not workspace. Bug: 318417510 Test: creating HotseatReorderUnitTest in follow up cl Test: TaplReorderWidgets Test: ReorderAlgorithmUnitTest Flag: NA Change-Id: Ic45029a244cb11f8d6775c50b90af9c56f01eaa3
