Construct a FrameBuffer for every buffer given in the camera3Request and add it to the libcamera Request on the appropriate stream. The correct stream is obtained from the private data of the camera3_stream associated with the camera3_buffer. Comments regarding supporting only one buffer are now removed, and FrameBuffers have their lifetime tracked in the Camera3RequestDescriptor to ensure they are released when the Request is completed.
