[ti-chi-bot]

This is an automated cherry-pick of #10133

What problem does this PR solve?

Issue Number: close #10289

What is changed and how it works?

1. Add a new item in tableSink called lastSyncedTs to record the latest commitTs received by sink module
2. Adjust the schedule part to pass all lastSyncedTs from tables and do aggregate at changefeed level to obtain a changefeed level lastSyncedTs
3. Add a new http api called api/v2/changefeeds/<changefeed-id>/synced to get the changefeed synced status.
4. Add related ut and ft for synced status calculation

Check List

Tests

• Unit test

• Integration test
  For integration test, I add the test for both normal cases and failure cases, such as tikv failed etc.

• Manual test (add detailed scripts or steps below)

  The http api looks like it:
  

  For performance test, we do pressure test on master and ours cdc and get the same sink output, which shows the PR have no impact on the performance.

• No code

Questions

Will it cause performance regression or break compatibility?

Do you need to update user documentation, design documentation or monitoring documentation?
