Fix setCanTurnScreenOn for a launching activity

Originally the flag set by Activity#setCanTurnScreenOn takes effect
when the activity will be resumed. But if the activity uses the method
while the creation of activity is needed, the flag doesn't have the
chance to be set before the check for applying it because the client
side creation is after the launching flow.

By adding the check for ActivityRecord#canTurnScreenOn at the same
path of FLAG_TURN_SCREEN_ON, it is able to turn the screen on when the
activity relayouts to be visible.

AppWindowToken#canTurnScreenOn is renamed to currentLaunchCanTurnScreenOn
because it only applies to the current launch and avoids confusion with
the one in ActivityRecord.
