@cqy123456 lgtm, what is the practical use case for this optimization? Basically, I wonder why this change was implemented for the brute-force search only

[cqy123456]

Raw data within a field is discontinuous in milvus. If the rows number in a raw data block is not aligned with 8, we need to copy a part of the bitset to knowhere. We also need to transfer Knowhere's default ID to an external ID. This PR is to enable Knowhere to obtain external IDs, reduce the copying of bitsets, and implement ID conversion.
