Disallow multi-selector arbitrary variants (#10655)
* Allow escaping in `splitAtTopLevelOnly`

* Correctly parse arbitrary variants that have multiple selectors

* Explicitly disallow multiple selector arbitrary variants

Now that we parse them correctly we can restrict them to explicitly supporting only a single selector

* Add test to verify that multiple selector arbitrary variants are dropped

* Add test

* Make prettier happy

* Fix CS

* Update changelog
