camera: Add boolean to HalStream for stream specific HAL buffer manager
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, HalStream.aidl - the parcelable returned by the camera HAL
for each stream configured now holds a boolean value, specifying
whether output buffers must be managed by the HAL or the camera
framework for the particular session configured.
