libcamera: v4l2_videodevice: Add V4L2PixelFormat class

The V4L2PixelFormat class describes the pixel format of a V4L2 buffer.
It wraps the V4L2 numerical FourCC, and shall be used in all APIs that
deal with V4L2 pixel formats. Its purpose is to prevent unintentional
confusion of V4L2 and DRM FourCCs in code by catching implicit
conversion attempts at compile time.

The constructor taking a V4L2 FourCC integer value will be made explicit
in a further commit to minimize the size of this change and keep it
reviewable.
