…ync support

Motivation and Context

This change is required to enable Semantic Kernel users to store and retrieve embeddings using Oracle databases. Currently, Semantic Kernel supports vector storage for several backends, but Oracle was missing. This connector solves that gap by providing full async support, native VECTOR type handling, and vector index management.

Description

This PR introduces a new Oracle connector for Semantic Kernel with the following features:

• Asynchronous upsert, get, delete and search operations for memory records.

• Native Oracle VECTOR type support for storing embeddings efficiently.

• Support for HNSW and IVFFLAT vector indexes for similarity search.

• Integration with Semantic Kernel collections, enabling semantic search and memory operations.

• Comprehensive unit tests to ensure correctness and stability.

The connector is designed to work seamlessly with existing Semantic Kernel memory abstractions and follows the same async patterns as other vector stores.

Integration tests have also been implemented and verified locally; however, they are not included in this PR because the current CI environment setup for Oracle Database support is unknown.
Once guidance is provided on Oracle DB availability in the CI pipeline, integration tests can be enabled and added in a follow-up PR.

Contribution Checklist
