…instead of `AnySequence`. This PR changes how `DiscoverableAsTestContent` enumeration works so that we can return `some Sequence` instead of `AnySequence`. We do so by removing the `~Copyable` constraint on the protocol, which subsequently causes the compiler to get confused and crash trying to represent `some Sequence<TestContentRecord<T>>` where `T: DiscoverableAsTestContent`.
