feat(bindings/java): Add StatOptions support for new options API

[geruh]

Which issue does this PR close?

Related to #6226.

Rationale for this change

This PR adds support for opendal::options::StatOptions conversion in the java bindings. This is part of the migration to the new options API outlined in RFC-6213 (#6213).

What changes are included in this PR?

• Added a complete mapping and conversion of opendal::options::StatOptions
• behavior tests mirroring Rust's async_stat.rs test suite
• Added the capabilities to support the options
• Instant to date time conversion which will aid in adding the read options.

Are there any user-facing changes?

Yes, users can now add options to their stat requests

While working on this, I noticed that some of the options are specific to presign. I think I can add those in a follow-up, as this PR was getting large.

However, it's worth noting that the current presign API doesn't follow the new xxx_option pattern and instead uses the with_ method chaining approach. Also, presign operations support the override* fields and a small subset of options (e.g., if_none_match). It may be worth investigating adding support for the options defined in #6213 to the presign operations.

Nice catch! I haven’t implemented that for presign yet, as it’s a bit more complex. Feel free to take it on if you’re interested!
