[CORE] Register native shuffles through backend API

[zhztheplayer]

Part of #6920.

So far Gluten's native shuffle implementations, including VL, CH, VL + RSS are activated by specifying corresponding shuffle manager types in Spark configuration.

However if we want to mix different native shuffles in the same Spark session even in the same query plan, as Spark only allows one shuffle manager to be registered (see also a related SPIP) yet, we should enhance out current approach by providing a registry of native shuffles internally under an umbrella shuffle manager. Then query planner could choose an optimal one among all the candidates.
