Problem Summary: Graceful shutdown with enable_graceful_exit_check could
report ASAN/LSan leaks after exec env destroy. The leak stacks showed pending
pipeline tasks in MultiCoreTaskQueue, scanner splits in
TimeSharingTaskExecutor, memtable flush tasks in workload group ThreadPool, and
QueryContext/ResourceContext retaining WorkloadGroup. ExecEnv stopped workload
group schedulers before fragment and load resources were released, and
WorkloadGroupMgr::stop only stopped scheduler threads without destroying
scheduler objects or their queued resources. Pending queues and executor task
maps could therefore retain query/load resources until process exit. This
change clears pending pipeline task queues on close, stops fragment/load
resources before final workload group scheduler shutdown, and makes final
WorkloadGroupMgr::stop destroy scheduler/thread pool objects so scan split and
flush task containers are released.
