libcamera: media_object: Add MediaLink string representations

Various parts of libcamera print the representation of a MediaLink by
inline joining the parts to make a string representation.

This repeated use case can be supported with a common helper to print
the MediaLink in a common manner using the existing toString() and
operator<< overload style to make it easier to report on MediaLink
types.

This implementation will report in the following style:

  'imx283 1-001a'[0] -> 'video-mux'[0]
