Add CUJs for closing All Apps.

CUJ_LAUNCHER_CLOSE_ALL_APPS_TO_HOME is meant to be the CUJ for closing All Apps through the home gesture/home button, which has different animations from closing apps in the same way.

By contrast, CUJ_LAUNCHER_CLOSE_ALL_APPS_SWIPE is the finger-tracking transition that dismisses All Apps by swiping down.
