libcamera: request: In addBuffer() do not fetch stream from Buffer

In the FrameBuffer interface the stream will not be available from the
buffer object as the buffer might be allocated externally. The
application needs to explicitly state which stream the buffer is being
added for to the request.

Extend the addBuffer() function to get this information explicitly from
the caller.
