Address LAUNCHER_APP_LAUNCH_FROM_ICON jank.

- Delay app launch animations by a frame, and skip logic to skip the first frame.
- Note the icon pressed state animation still occurs, so there is still some
  visual feedback for the user that something is happening.

Bug: 181901105
Test: ensure animation still looks smooth (using window animation scale & record in slow mo)
