feat(java): support building vector index distributively

[majin1102]

Note:

1. Reposition merge_index_metadata so that Java dataset could directly call mergeIndexMetadata for vector indexes.
2. Add centroids to IvfBuilderParams and codebook to PqBuilderParams to make distrubitively creating vector indexes work
3. Add a new index package under tests to have index tests.
4. This PR update Cargo.lock due to the intruduction of perf: improve FTS indexing perf and reduce memory footprint #5650.
