Do the same size-configuration bucketing on both server and client

Otherwise they get out-of-sync and sometimes AR will not relaunch
the app, but the app client will think it needs to be relaunched

Bug: 181697795
Test: app configuration tests pass.
      With 3-button nav, open app in split and observe launcher
      reconfigure properly.
