			First, this adds an overload of PrimitiveString::create for StringView. This overload will throw an OOM completion if creating a String fails. This is not only a bit more convenient, but it also ensures at compile time that all PrimitiveString::create(string_view) invocations will be handled as String and OOM-aware. Next, this wraps all invocations to PrimitiveString::create(string_view) with MUST_OR_THROW_OOM. A small PrimitiveString::create(DeprecatedFlyString) overload also had to be added to disambiguate between the StringView and DeprecatedString overloads.
