* Layout hotseat icons from the end instead of the start
* IME down and system back arrow are now separate views
Bug: 191399224
Test: Tested w/ RTL + LTR in gesture
and 3 button nav w/ and w/o IME

This shows back and IME switcher when in app taskbar
and IME is visible.
This doesn't remove the system bar just yet (will
show overlap). Next CL will remove the system IME buttons
so only launcher IME buttons show.

Organize existing properties as follows:
- TaskbarViewController contains properties affecting TaskbarView (though child icons are still supplied by TaskbarHotseatController)
- TaskbarDragLayerController contains properties related to TaskbarDragLayer itself
- Renamed NavbarButtonUiController to NavbarButtonsViewController, following the pattern of TaskbarViewController and TaskbarDragLayerController
- TaskbarControllers contains the different controllers to make it easier to construct, initialize, destroy, and pass them around
- Removed TaskbarIconController as its responsibilities were moved to more specific controllers
Test: compiles and runs, manually tested
