Jayant Chowdhary 644676a583 camera: Add support for toggling HAL buffer manager as a result of session configuration ...

Currently, whether the HAL buffer manager is used or not is decided
based on the presence of a static camera characteristics key -
ANDROID_INFO_SUPPORTED_BUFFER_MANAGEMENT_VERSION. This behavior cannot
be toggled depending on stream configuration / session parameters.

The HAL buffer manager does reduce memory consumption at the cost of
extra IPC calls, which may not be always desirable.

Therefore, a new API - 'configureStreamsV2()' is introduced to give the
camera HAL the ability to inform the camera framework whether it must
use the HAL buffer manager for the particular session configured.
