-Add a new app ops helper to make testing easier.
-Consolidate app identity within CallerIdentity class.
-Remove location age restriction for coarse locations, was a bit
arbitrary.
-Remove listener identifiers from LM. These were not being properly
propagated and add a lot of binder overhead with what appears to be
little benefit since we have featureIds, which contain much better
information.
-Remove appops checks from some GNSS APIs that shouldn't require it.
-Move location fudger into location providers and reset them after mock
providers are used so that offset information cannot be leaked.
