Remove NotificationPanelView from LockSection

The code to explictly remove lock_icon_view in the LockSection
Composable is a remanant from lecacy UI, so it is removed. Injecting
NotificationPanelView when scene container is enabled also crashes
SystemUI.

Test: verified SystemUI does not crash with LockSection injected and
      scene container enabled
Test: verified keyguard works correctly with scene container disabled
