Issue Number: close #9714

Problem Summary:

Checkout the logging in issue.

From "Invalid page id, entry not exist [page_id=451.26] [resolve_id=451.26]" and the StackTrace DB::DM::Segment::restoreSegment(std::__1::shared_ptr<DB::Logger> const&, DB::DM::DMContext&, unsigned long) dbms/src/Storages/DeltaMerge/Segment.cpp:427 we can know that something is wrong when restoring the StableValueSpace of Segment. After adding some debugging message, we know that the error comes from restoring table_id=451, segment_id=8822.

Then dump the BlobData from PageStorage "meta". We found that the last two records persisted on disk is invalid as a SegmentMetaInfo.

Before the error happen, we saw that the table_id=451, segment_id=8822 had applied a SegmentUpdateMeta task after DeltaMergeStore::shutdown. Segment::replaceStableMetaVersion will access to a already shutdown PageStorage. Causing the WriteBatch wrote broken data.

What is changed and how it works?

Storages: Shutdown the LocalIndexScheduler before shutting down PageStorage/DeltaMergeStore
* Add a method `LocalIndexerScheduler::shutdown()` and ensure the running task are all finished before shutting down the GlobalPageStorage in `ContextShared::shutdown()`.

• Add a method LocalIndexerScheduler::shutdown() and ensure the running task are all finished before shutting down the GlobalPageStorage in ContextShared::shutdown().
• Add error message about the segment_id when restoreSegment failed
• Add debugging tool command for reading the BlobData from PageStorage instance

Check List

Tests

• Unit test
• Integration test
• Manual test (add detailed scripts or steps below)

1. Deploy a cluster with vector data
2. Create a script to run add/drop vector index repeatly 
`alter table vector_bench_test drop index idx_emb_l2;`
`alter table vector_bench_test add vector index idx_emb_l2 ((VEC_L2_DISTANCE(embedding)));`
3. Create a script to restart tiflash repeatly
4. Check whether tiflash restart successfully
5. TiFlash restart successfully after running those 2 scripts for 7 hours
