Extend V4L2Device to provide a tryFormat function. This can be used to check a
format against a V4L2 Device to determine a suitable configuration.

Utilise this in the UVC pipeline handler so that we can validate configurations
on any UVC web cam.

  libcamera: v4l2_device: Add tryFormat support
  test: v4l2_device: Extend formats test with tryFromat()
