qdrant: Updated class check in Self-Query Retriever factory (#25877) ## Description - Updates the self-query retriever factory to check for the new Qdrant vector store class. i.e. `langchain_qdrant.QdrantVectorstore`. - Deprecates `QdrantSparseVectorRetriever`, since the vector store implementation natively supports it now. Resolves #25798
