Subject: [PATCH] Adds UniversalSmartspaceUtils to be shared between Launcher
 and SysUI.

Some initial helper methods include ones to build the intent for
Launcher to send its SurfaceView to SysUI, and for SysUI to
retrieve the necessary components (SurfaceControl and InputToken).

Test: Builds; used new method in Launcher.
Bug: 141701658
