Defintions for 2 GNSS Android P features: - The Duty Cycling OFF API to enable high accuracy applications development - The Low Power Mode GNSS API to save power when indoor VTS tests for both features. Bug: 64009176 Test: hidl-gen/compile/build checks, no functional tests yet Change-Id: I4a41757e4ad6747f22a7e9ae1e0024f083c5fbfb
