Remove all calls to getComponent(CommandQueue.class).

Makes AuthController, GlobalActionsComponent, InstantAppNotifier,
SizeCompatModeActivityController, and TvStatusBar all injectable.

Prior to this CL, CommandQueue contained within it a SystemUI object
that it used to start itself up and add itself to components. With
this change, the SystemUI object is no longer necessary, as Dagger
will ensure that a CommandQueue is available to those who need it.

Test: atest SystemUITests
