bindings: make ^Q and M-Q available also in the help viewer 

As the help viewer is almost a normal buffer, commands that make sense
-- like searching backwards, and searching the previous occurrence --
should work in the help viewer too.

In addition, show all Search commands prominently in the help lines of
the help viewer, so that users are likely to notice them and will maybe
infer that they work in the editor itself too.

This fixes https://savannah.gnu.org/bugs/?54368.
