AK+Everywhere: Remove the null state of DeprecatedString
This commit removes DeprecatedString's "null" state, and replaces all its users with one of the following: - A normal, empty DeprecatedString - Optional<DeprecatedString> Note that null states of DeprecatedFlyString/StringView/etc are *not* affected by this commit. However, DeprecatedString::empty() is now considered equal to a null StringView.
