Support the ability to resume `onSnapshot` listeners in the CSR phase based on serialized `DataSnapshot`s and `QuerySnapshot`s built in the SSR phase. Allow Firestore result types to be serialized with `toJSON` and then deserialized with `fromJSON` methods on the objects. `DocumentSnapshot` and `QuerySnapshot` deserialization methods will be standalone, tree-shakable functions `dataSnapshotFromJSON` and `querySnapshotFromJSON`.
