Fix an issue with nav bar translations not being updated

- There are flows where the shared taskbar state is updated prior
  to being destroyed, and not updated to the latest values when
  the taskbar is recreated.

  ie.
    unfolded -> lock screen -> LauncherTaskbarUiController's
      mTaskbarInAppDisplayProgress[SYSUI_SURFACE_PROGRESS_INDEX]
      is set to 1 due to the notif shade (lockscreen) showing.
      This is written into TaskbarSharedState's sysuiStateFlags
      and inAppDisplayProgressMultiPropValues.
    fold -> TaskbarActivityContext is destroyed
    unlock -> TaskbarManager and TaskbarSharedState's
      sysuiStateFlags are updated while the device is folded
    unfold -> TaskbarActivityContext is recreated and initialized
      which restores from the shared state's
      inAppDisplayProgressMultiPropValues. It also tries to reapply
      the shared state's sysuiStateFlags, but this doesn't update
      inAppDisplayProgressMultiPropValues because the state's
      "enabled" state is not updated (default is no flag set, and
      lockscreen sysui state is not set anymore).
    -> The restored inAppDisplayProgressMultiPropValues value
       results in the wrong translation.

- Note that after the above, the NavbarButtonsViewController state
  is actually correct and reflects the SysUI state, but the
  LauncherTaskbarUiController state is wrong.  This CL tries to
  manually update the ui controller to the correct state when it
  is recreated.
- CL also fixes a separate issue where LauncherTaskbarUIController
  could potentially overwrite the saved state progresses while
  restoring them due to the state callback being called

Test: Unfold -> Lockscreen -> Fold -> Unlock -> Unfold and ensure
      the buttons are translated correctly
