Camera2/3: Fix deadlock when starting recording before preview.

Move 3A notification synthesis for HAL3 devices from
Camera3Device::processCaptureResult to Camera2Client's
FrameProcessor. This will ensure that calls to processCaptureResult
from HAL can never block on Camera2Client internal mutexes.
