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.

We were checking 'info' twice and not checking 'msgs'. So we
fix that up, and fix a typo in the message.

Android T migrated the HAL interface to AIDL, but the reference HAL
was never updated to use AIDL. This CL migrates the reference
HAL implementation for external cameras to use AIDL as well. The
external HAL uses V4L2 standard to expose USB cameras to the
cameraserver.
The reference HAL implementation for internal camera was dropped
because it is not possible to write a generic HAL that works with some
large percentage of internal cameras.

Test: Existing CTS tests pass with external camera connected.
