AK: Add support for "debug only" formatters
These are formatters that can only be used with debug print functions, such as dbgln(). Currently this is limited to Formatter<ErrorOr<T>>. With this you can still debug log ErrorOr values (good for debugging), but trying to use them in any String::formatted() call will fail (which prevents .to_string() errors with the new failable strings being ignored). You make a formatter debug only by adding a constexpr method like: static constexpr bool is_debug_only() { return true; }
