libcamera: request: Provide a sequence number
Provide a sequence number on Requests which are added by the pipeline
handler.
Each pipeline handler keeps a requestSequence per CameraData and
increments everytime a request is queued on that camera.
The sequence number is associated with the Request and can be utilised
for assisting with debugging, and printing the queueing sequence of in
flight requests.
