Evilify and add cider-repl-history-mode keybindings (#14842)

Cider provides the possibility to search the REPL history, for which it opens
the history in a read-only buffer (which as usual, is best initialized in
evilified state).

This commit evilifies the cider-repl-history-mode buffer and defines some common
sense cider-repl-history-mode keybindings.
