Fix Taskbar unlock transition 

- There are multiple signals that come just after FLAG_DEVICE_LOCKED
  is removed, and those should still be considered part of the unlock
  transition. We already did this for TaskbarStashController so I copied
  it to TaskbarLauncherStateController.
- Also animate when changing SYSUI_STATE_OVERVIEW_DISABLED, since this
  happens when the device is locked/unlocked and changes the visibility
  of TaskbarView icons.

Test: manually unlock over both home screen and in-app, verify clean
transition without jump (e.g. Hotseat is immediately visible as part of
Workspace, and Taskbar fades in during unlock to an app)
