feat(java): expose additional Operation::Update fields to bindings

[wayneli-vt]

This PR enhances the Java bindings for Operation::Update as a follow-up to #4589.

While #4589 introduced new fields to the Rust Operation::Update struct, the Java bindings were still missing support not only for those new fields but also for the existing fields_modified field, which is crucial for handling column modifications.

Specifically, it adds support for the following fields:

  Update {
      // ...
      /// The fields that have been modified
      fields_modified: Vec<u32>,
      // 👇 New fields from #4589
      /// The fields that used to judge whether to preserve the new frag's id into
      /// the frag bitmap of the specified indices.
      fields_for_preserving_frag_bitmap: Vec<u32>,
      /// The mode of update
      update_mode: Option<UpdateMode>,
  }
