AK: Add operator""_{short_,}string to create a String from a literal
We briefly discussed this when adding the new String type but couldn't settle on a name. However, having to use String::from_utf8() on every literal string is a bit unwieldy, so let's have these options available! Naming-wise '_string' is not as short as 'sv' but should be relatively clear; it also matches '_bigint' and '_ubigint' in length. '_short_string' may be longer than the actual string itself, but it's still an improvement over the static function :^) Since our C++ source files are UTF-8 encoded anyway, it should be impossible to create a string literal with invalid UTF-8, so including that in the name is not as important as in the function that can receive arbitrary data.
