### What changes were proposed in this pull request? Try to fix ApiWorkerResourceSuite::threadDump UT stuck issue. 1. Using program way to get thread dump. Related code copied from apache/spark https://github.com/apache/spark/blob/v3.5.1/core/src/main/scala/org/apache/spark/util/Utils.scala https://github.com/apache/spark/blob/v3.5.1/core/src/main/scala/org/apache/spark/status/api/v1/api.scala ### Why are the changes needed? I found that sometimes the UT stuck for threadDump api: For example: https://github.com/apache/celeborn/actions/runs/8462056188/job/23182806487?pr=2428 <img width="1291" alt="image" src="https://github.com/apache/celeborn/assets/6757692/f39d7bb9-6e31-4ce3-a573-1ff86f335318"> <img width="762" alt="image" src="https://github.com/apache/celeborn/assets/6757692/437592dd-fc9c-404d-a452-834fcf630bd1"> threadDump api UT is new introduced in [CELEBORN-1317](https://issues.apache.org/jira/browse/CELEBORN-1317). Before there is no UT to cover that, and now it stuck sometimes. And for getThreadDump, before it leverages processBuilder to get the thread info. I wonder that the process is stuck because of some unknown reason, so, in this pr, we try to use program way to get thread info. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? UT.  Closes #2429 from turboFei/thread_dump.
