This is an automated cherry-pick of #50037

What problem does this PR solve?

Issue Number: close #50012

Problem Summary:

The second parameter of tablecodec.DecodeHandleInUniqueIndexValue indicates whether index KVs belong to a clustered-index table. Previously, it was always false, causing decoding error and panic.

What changed and how does it work?

  • Set the parameter properly.
  • In order to pass the check like BatchGet req does not set the resource tag, tid: 123, stack: goroutine 20153 [running], I also set the resource group tagger by the digest of all SQLs.
  • Add an integration test.

Check List

Tests
