Detect potential WindowConfiguration change at onApplyWindowInsets

- Invoke onConfiguration when receiving inset changes
- In Laucnher/RecentsActivity onConfiguration, additionally detect for windowConfiguration's rotation change; if Configuration stays the same, it'll be ignored.

Bug: 240730723
Test: manual on 90/180 degree rotation in Launcher and RecentsActivity
