libcamera: v4l2_pixelformat: Return a format list in fromPixelFormat()

As we prepare to associate multiple V4L2 FourCC to a single libcamera
format, make the V4L2PixelFormat::fromPixelFormat() return a list of
formats and convert all its users to pick the first one.

This change prepares to re-introduce V4L2VideoDevice::toV4L2PixelFormat()
which will instead match the list of V4L2 FourCC against the formats
supported by the video device.

While at it, reword the V4L2PixelFormat::fromPixelFormat() documentation
to distinguish between planar/multiplanar and contiguous/non-contiguous.
