Clean up external HAL reference implementation.
This CL cleans up the reference external HAL implementation.
Specifically, it makes the following changes:
- Removes mSupportBufMgr from ExternalCameraDeviceSession as it never
needed to be used.
- Makes ExternalCameraOfflineSession final to prevent other classes
from accidentally inheriting from it. ExternalCameraOfflineSession
calls the virtual function `close()` on destruction which depends on
the implementation details of other virtual functions.
