Add a menu to cider-repl-history-mode

The mode bound 13 commands but had no menu, so search/filter and
delete/undo operations were undiscoverable without reading the
source.  Add a 'REPL History' menu grouped into insert, navigate,
search, modify, and quit sections.

 ### Bugs fixed
 
+- `cider-repl-history-mode` now has an `easy-menu` ("REPL History") covering insert, navigation, search/filter, refresh/delete/undo, and quit.
 - `cider-log-mode` now has an `easy-menu` ("CIDER Log") covering event inspect/print, navigation, and the framework/appender/consumer/event management commands previously only reachable via the `C-c M-l` prefix.
 - `cider-macroexpansion-mode`, `cider-repl-history-mode`, and `cider--debug-mode` docstrings now include `\\{...-map}`, so `C-h m` (`describe-mode`) lists the active key bindings instead of just a one-line description.
 - `cider-repl-mode-menu` now lists `cider-repl-history` ("Browse REPL input history", `C-c M-p`) alongside the other Browse entries.
