[BugFix] Capture resource group for scan task (backport #51121)

[mergify]

Why I'm doing:

The scan task queue is a two-level queue:

• First level: The workgroup_entity queue, which stores raw pointers to workgroup_entity. These workgroup_entities are owned by their workgroups.
• Second level: The task queue, where each workgroup_entity contains an internal task queue. Each task within this queue also has a raw pointer to the associated workgroup.

When retrieving a task from the scan task queue, the process first accesses the workgroup_entity and then extracts a task from the internal task queue of that workgroup_entity.

However, the lifecycle of a scan task can be longer than that of the corresponding pipeline driver and workgroup. When executing the SQL command DROP RESOURCE GROUP, the workgroup is deleted once all associated pipeline drivers have completed.

This can lead to a situation where the workgroup_entity and its corresponding tasks still reside in the scan task queue, but the workgroup itself has already been released. In such cases, accessing the workgroup_entity results in a "use-after-free" error.

What I'm doing:

To prevent this issue, each task should hold a shared pointer to the workgroup. This ensures that the workgroup will not be deleted as long as there are tasks in the scan task queue referencing it.
