libcamera: ipu3: Connect viewfinder's BufferReady signal
The viewfinder and main output require identical logic for buffer and
request completion. Connect the viewfinder bufferReady signal to the slot
and handle requests for both main output and viewfinder there.
Update the slot logic to complete the request only when the last buffer
has completed, and make sure to complete requests in the same order they
have been queued to the pipeline handler.
