Camera: Switch camera2 to auto-gen C++ binder interfaces

 - Move camera service AIDL files to frameworks/av
 - Build C++ interface stubs with AIDL tools
 - Add necessary native-side parcelables and update existing ones
 - Remove manually-written stubs, rearrange remaining manual stubs
 - Adjust implementations to work with auto-generated stubs
   - Adjust method signatures for auto-gen differences
   - Add rich error messages using binder::Status
