libcamera: v4l2_videodevice: provide hasMediaController()
The V4L2Capability has helpers to interogate the capabilities
of a device.
V4L2VideoDevice::enumPixelformats accesses the raw capabilites to check
if the device is supported by a MediaController device.
Provide a helper, and update the usage.
