   ### What problem does this PR solve?
   
   Issue Number: close #xxx
   
   Related PR: https://github.com/apache/doris/pull/59262
   
   Problem Summary:
   
   During BE graceful shutdown, cancel_worker cancels running queries via 
_get_all_running_queries_from_fe, so clearing _query_ctx_map_delay_delete here 
won't cause RF consumer to hang. Without this clear, QueryContext destruction 
in ~FragmentMgr() may attempt to remove itself from _query_ctx_map_delay_delete 
while the map is being destructed, causing undefined behavior.
   
   stack:
   ```
   ~FragmentMgr
       ~_query_ctx_map_delay_delete
           ~QueryContext
               FragmentMgr::remove_query_context
                   _query_ctx_map_delay_delete.erase() ⚠️call function of 
object that is being destructed
   ```
