manuals: improve apropos {console, keyboard}

[concussious]

I'm trying to make "apropos -s 1 keyboard" and "console" look nice and tell the console user what they're probably looking for, while distinguishing what they're not looking for (graphical environment tooling, serial console tooling, I dont know). Patches sent to freedesktop and libxkbcommon for that effect too. EDIT: all patches upstream accepted.

~~But, pointy hat to me: my proposed vidfont description is 81 characters. This wraps in man, which I think looks fine, but wraps in apropos, which looks horrible, on 80 char "standard console" including stock xterm; seems unacceptable regression. Ideas?~~

I don't know how it is on other people's boxen but in my house terminus bsd console (vt) is 85 char wide and is unaffected by this proposed regression.

AIUI for man page changes which do not change meaning the .Dd doesn't need to be bumped -- e.g. a typo fix, minor clarification etc.

I usually don't, and actually prefer not to on some of these really old pages because they still talk about sc like it isn't deprecated, and even put not to in CONTRIBUTING, but last time Warner said Nd change bumps it, and I don't want to be bad and make him do it for me or groan to see my PR.

Edit: I'm absolutely happy to do it either way, I want to be doing it correctly and be a blessing here.
