2024-10-17: Built-in vectorizer for all indexes

This release includes updates to the code that sets up the search index and optional integrated vectorization feature.
Going forward, all indexes will have an Azure OpenAI vectorizer by default, even if not using integrated vectorization. That makes it easy to issue queries in the Portal or from the SDK without having to compute the embedding yourself. It will also make this index more compatible with the VoiceRAG demo.

For those of you using integrated vectorization, it should be easier to use that feature with the newer embedding models now.
