Hi,

This change essentially superscedes the work done in 
https://patchwork.libcamera.org/project/libcamera/list/?series=2978.

I've moved the dequeue timeout functionality into the v4l2_videodevice class,
allowing any pipeline handler to use the functionality. This change also allows
us to set a timeout on any device node easily.

Thanks,
Naush
