ref-manual: Add "devtool extract/sync" explanation

From: Vincent Kriek <vincent@coelebs.dev>

Documentation describing the devtool extract and devtool sync commands
were not present. This patch adds basic explanations how the commands
work and why you could use them.

Your patch does apply, but actually, the current documentation already 
mentions "devtool extract" and "devtool sync". See 
https://git.yoctoproject.org/yocto-docs/tree/documentation/ref-manual/devtool-reference.rst#n224

You may have started from an older version of the documentation, or just 
overlooked  such sections.

Unless I'm mistaken, you may merge your changes with the existing 
descriptions, keeping the best of both. Could you send a new version?

Thanks in advance
Cheers
Michael.
