doc-rst: migrated media build kernel-cmd directive

From: Markus Heiser <[e-mail]>

Remove the media-Makefile and migrate the ``.. kernel-include::``
directive to the new ``.. kernel-cmd::`` directive.

To avoid breaking bisect, this patch includes the required changes to
the implementation (script ``parse-headers.pl``) and the content (*.rst
files).
