[threaded-animations] crash in

Reviewed by Simon Fraser.
We need to make sure to check for both `filter` and `backdrop-filter` when
considering
animations and keyframes in `RemoteAnimationStack::longestFilterList()`
otherwise we will
fail to animate `backdrop-filter` and crash with an empty `FilterOperations`.
