Introduce CompatUIRequest to show restart dialog

Currently, CompatUIController is designed so that any app-compat
UI change can be triggered with onCompatInfoChanged(). This can be
done because all the information needed by CompatUIController is
computed in WMCore.

However, our new restart menu is implemented in window decoration,
and requests the restart dialog via user action in the app handle
menu. So we need a way for other WMShell components to trigger
some UI changes in CompatUI.

This change introduces CompatUIRequest. It meets the above
requirement for the restart menu, while it's generic enough in
case we may need to do something similar for other features in the
future. The code pattern follows the existing CompatUIEvent, but
it just defines the counterpart in the common request/event model.

Note that, with this change, the restart dialog is allowed to be
shown in desktop mode if isRestartMenuEnabledForDisplayMove() is
true.
