bindings: allow toggling the help lines at several prompts and in browser

Now the help lines can be toggled not only while editing, but also at
the Read (^R), Write (^O), Execute (^T), Search (^W), Replace (M-R),
Goto (^/), and Yesno prompts, and also in the file browser and when
searching for a file name.  The help lines cannot be toggled in the
help viewer, nor when searching in a help text, nor in the linter,
as these three things force the help lines to be on.

Furthermore, the 'nohelp' function can be rebound in all relevant
menus (default binding: M-X).

This fulfills https://savannah.gnu.org/bugs/?58471.
