Move #mSwitchingController to UserData
With this CL
InputMethodManagerService#mSwitchingController
to UserData so that each user can keep maintaining its own instance.
The observable behavior should remain to be the same for single user
mode. For experimental concurrent multi-user mode, the controller is
now properly initialized in
IMMS#experimentalInitializeVisibleBackgroundUserLocked().
