Provide a constructor for StreamBuffer and use that while populating Camera3RequestDescriptor::buffers_ vector. Also provide the default move-constructor (required as StreamBuffer is stored in a vector in Camera3RequestDescriptor) and destructor for the StreamBuffer struct. Also declare a default move assignment operator and disable the copy constructor and move operator explicitly with LIBCAMERA_DISABLE_COPY(). While at it, initialize pointers members in the StreamBuffer struct to nullptr, with StreamBuffer::status set to Status::Success by default.
