Add a new boolean resource to reset the AirPlane mode after during boot.

- This resource is added specifically to be used for automotive devices where if the device exits from safemode and boots into normal mode, the airplane mode remains enabled. And there is no UI on automotive devices to disable the Airplane mode.
- The value will be overlayed to true for automotive devices.

Bug: 182523956
Test: Override the config and check if airplane mode is disabled in the normal mode.
