common: add watchdog-debugging document

I think this should either go into the dev wiki (instead of common) or it should be combined with the existing "independent watchdog" page which is in common. https://ardupilot.org/copter/docs/common-watchdog.html

I've moved it into dev - only devs are going to be interested in it - I expect it will get a link from that other page, 'though.

when its ready, I can check formatting and add a link from the other page...

It's a bit odd to have the page called "common-" when it's in the dev section... I think the file itself should also be renamed to remove the common-.

Done.

What it really needs is much better content....

I think this should go in as-is and can be expanded on more in future
