Pull up all apps interaction

First phase implementation: dragging and animation interaction is implemented
namely in two classes. ScrollGestureDetector and AllAppsTransitionController.

FeatureFlag.LAUNCHER#_ALL_APPS_PULL_UP will be true for only AOSP and
not in the extending builds. This way, we can safely iterate without
turning it on the shipped ready version.
