Extends the criteria width of 2-pane mode

Follow UI spec, we extend criteria width from 600dp -> 720dp

Original code checks if there is only one Activity in
Activity stack to decide if it's a deep link intent,
it has problem at configurationChange.

This change checks if the intent is from Settings app
itself to decide if it's a deep link intent.

Bug: 197716926
Bug: 199808997
Test: Build apk and run on the device.
