This avoids making an extra copy of the escaped string. Note that jsonrpc_command_add() no longer accepts usage strings containing invalid escape sequences. (Previously, it would quietly accept such a string without unescaping anything.) Changelog-None

Note that #7013 did some of this work, but the neating is still appreciated! |

Plugins can send arbitrary strings in
lognotifications. Lightningd was logging these strings without unescaping them, leading to ugly backslashes in the log. Unescape the strings before logging them.Note: This PR depends on and subsumes #8415.
