The Android Automotive trout device uses GNSS HAL for fetching location data from a live GNSS adapter, not a mock file. We also have an established naming convention for console port names that is carried over from the Bluetooth use case. Add support for a vendor uart port for GNSS in addition to the existing Cuttlefish debug property, in order to enable trout to establish a connection to the host GNSS agent Bug: 213489959 Test: build flash and boot Change-Id: Id2d2134bb6ea60adef1072295c4f623463bfb010
