Add new int8_hsnw index type for int8 quantization for HNSWedit

This commit adds a new index type called int8_hnsw. This index will automatically quantized float32 values into int8 byte values. While this increases disk usage by 25%, it reduces memory required for fast HNSW search by 75%. Dramatically reducing the resource overhead required for dense vector search.
