.Net: Adds a memory connector for Azure Cosmos DB for NoSQL (#6148)

### Motivation and Context

Azure Cosmos DB is adding Vector Similarity APIs to the NoSQL project,
and would like Semantic Kernel users to be able to leverage them.

### Description

This adds a Memory Connector implementation for Azure Cosmos DB's,
including support for the new vector search functionality coming soon in
Cosmos DB. It is mostly based off the existing connector for Azure
Cosmos DB for Mongo DB vCore.
