### What problem does this PR solve?
Issue Number: close #xxx
Related PR: #62954
Problem Summary: Backport #62954 to branch-4.1. During BE shutdown,
FragmentMgr clears `_query_ctx_map_delay_delete`. The old
`ConcurrentContextMap::clear()` destroyed map values while holding the shard
mutex. Releasing the last `QueryContext` reference can run
`QueryContext::~QueryContext()`, which calls back into
`FragmentMgr::remove_query_context()` and attempts to erase from the same
delay-delete map, causing `std::system_error` with `Resource deadlock avoided`
and then BE abort. The fix swaps each shard map into a local map under the
lock, releases the lock, and only then destroys the values.
### Release note
None
### Check List (For Author)
- Test:
- Manual test: `git diff --check upstream/branch-4.1..HEAD`
- Manual test: `./build-support/check-format.sh`
- Unit Test: `./run-be-ut.sh --run
--filter=FragmentMgrDelayDeleteMapTest.*` was started locally but not completed
because it triggered a full ASAN_UT rebuild (`14920` ninja targets); the run
was interrupted before test execution.
