Disable swipe boost and preferred apps for certain cases

This change is a combination of the following changes
   (a) Disable swipe boost and preferred apps for certain cases
   (b) Add Game boost & modify launchboostv2 invocation.

(a) swipe boost:
    This change disables swipe boost for the following cases:

    1. If top app is a game, swipe boost is completely disabled.

    2. Swipe boost is disabled for horizontal fling motion.

    Preferred Apps:
    This change also helps preferred apps filter games. An app
    will not start as empty if that app is detected to be a game.

(b) Add Game boost & modify launchboostv2 invocation.

    Trigger LBv2 from where LBv1 is triggered. Recent app
    behavior changes cause oringinal LBv2 in startProcess
    to not trigger. This is fixed. Detect if app is a game
    & trigger game boost, for faster game launch latency.
