android: post_processor: Introduce a PostProcessor interface
Introduce a PostProcessor interface for the streams that require any kind of processing (refer to CameraStream::Type) for their consumption by the HAL layer. The PostProcessor interface can be configured via configure() and the actual processing can be initiated using process(). The post-processing layer can be extended to have multiple post processors for various stream configurations. As of now, we only have one post processor (JPEG), hence the subsequent commit will port its function to this interface.
