[PATCH i-g-t 3/3] gitlab-ci: Add MkDocs documentation support

[Pawel Sikora]

From: Pawel Sikora <pawel.sikora at linux.intel.com>

This commit ensures two things:

 * The API reference manual is built and copied to the MkDocs documentation directory.

 * The MkDocs documentation (from the docs directory) is also built.

As a result, the existing API reference manual will still be available via an internal
link in the MkDocs documentation.
(Note: the API reference will retain its original theme for now.)

A relative link to api_reference/index.html is included in the MkDocs navigation.
This file will be generated by the deploy job after the API reference manual is built.

After both builds are complete, all content will be copied into the site directory
and then manually moved into public, for hosting on freedesktop GitLab Pages.
