camera: Migrate ndk_vendor client implementation to AIDL.

With HIDL deprecated, cameraservice's vndk client interfaces have been
updated to using AIDL. This CL drops support for the HIDL vndk client
interface.

When vendor partition is rebuilt for future version of android, it
should automatically pick up the new new client implementation.
Cameraservice will continue to support both HIDL and AIDL vndk clients.

The changes are simple 1:1 mapping of HIDL interface logic with AIDL
interface logic.
