ttl: implement ttl job schedule framework (#39472)

[ti-chi-bot]

This is an automated cherry-pick of #39472

What problem does this PR solve?

Issue Number: close #39471

Problem Summary:

Implement a ttl job schedule framework. It reads information from the info schema and the mysql.tidb_ttl_table_status, gets the job to run and schedule them to a scan worker.

The implementation of variable settings, scanWorker and delWorker are left for future development.

What is changed and how it works?

For most parts, the job manager is split from the original demo: https://github.com/pingcap/tidb/pull/39320/files. It implements the following feature:

1. The most fundamental one. Let the job run on the worker.
2. Support graceful shutdown with the context from domain.
3. Allow collecting the errors from the tasks, and storing them into the table when the job is finished.
4. Allow cancelling the running jobs.

This pr left a lot of TODO for system variables. They are left in #39727.
