### Why are the changes needed? Virtual threads are mature in JDK 21, which Kyuubi already supports. As an I/O-bound gateway, Kyuubi is a good fit for this execution model. This PR makes a small first step by adding optional virtual-thread support to the server-side Thrift Binary frontend. It is disabled by default and does not affect engine frontends or other executors. The implementation preserves the worker concurrency limit and rejection behavior while retaining compatibility with older JDKs. See #7655 for the motivation and benchmark results. ### How was this patch tested? - Targeted suites passed on JDK 11 and JDK 21. - `dev/reformat` - `git diff --check` - Kyuubi Server fast package build. - Five-minute A/B test with real Spark SQL. ### Was this patch assisted by generative AI tooling?
