Removing WireGuard Support From FreeBSD Base

[Gordon Bergling]

I am not sure, if the removal is a great idea, a removal from
releng/13 and stable/13 - possibly yes, but from main?

This is still -CURRENT and -CURRENT should be central place for development,
even if we have phabricator for review.

If the complete backout is happening, please don't forget the manual
page. I have spend a lot of time on it, while OpenBSD made a good
template.
