IGNITE-14187 .NET: Add thin client DataStreamer

**Server:**
* Add ClientDataStreamerStartRequest, ClientDataStreamerAddDataRequest to the thin client protocol
* Fix security permission checks in the DataStreamerImpl
* Add ClientStatus.INVALID_NODE_STATE

**.NET thin client:**
* Add `IIgniteClient.GetDataStreamer` API (thread safe)
* Implement stateless partition-aware variant (see IEP): stateful mode shows similar performance but with greatly increased complexity
