The `deprecated_format` helper is a thin wrapper to map results from AK::vformat to a throw completion. This will let us try to throw on OOM conditions rather than just blowing up. Note it's called `deprecated_format` as we will likely end up adding a method named just `format` to return `ThrowCompletionOr<String>`, when we begin the migration from DeprecatedString->String for LibJS.
