a great feature for debug executor hang! It's better to have a config to switch on/off for this feature?

In Vanilla Spark WebUI, it is easy to get the current java jstack, which is very helpful to diagnostic the hang/slow problems. But when it comes to Spark on Gluten, the jstack is meaningless since all heavy jobs are under JNI call.
This PR adds the same ability to capture native C++ stack traces from executors directly from the Gluten SQL tab in the Spark UI. It introduces an executors overview with a per‑executor "C++ Stack" action and a dedicated "Gluten C++ Stack" status page that streams the collected stack output.
There are two modes, sync and async. The async mode is mainly because gdb data collection typically takes a long time, exceeding the yarn proxy timeout in our environment.
