Ensure recents layer is moved between the 3p launcher and the apps

Browse Source 
- The recents activity needs to be layered above the 3p launcher, but
  below the currently running applications since it draws an opaque scrim
  in its window
- Also adding the layering to the logs to make it easier to see how
  the surfaces are set up at the start of a recents transition

Bug: 286242134
Test: Enter overview from an app with a 3p launcher
