Add a `.clearhistory` REPL command that clears the in-memory session history and truncates the persisted history file when one is configured. Any pending debounced flush is cancelled first so it cannot rewrite the file after it has been cleared. Fixes: nodejs#63905 Signed-off-by: Paul Bouchon <mail@bitpshr.net>

.clearhistoryREPL command that clears the current session history, both in memory and in the persistent history file when one is configured.It clears the in-memory history array, resets the navigation index, and truncates the backing file through the open handle. Any pending debounced flush is cancelled first so it cannot rewrite the file after it has been cleared.
