This is an automated cherry-pick of #57756

What problem does this PR solve?

Issue Number: close #57631

Problem Summary:

See more at #57631 (comment)

We need to support updating the stats of only a few tables within the update function. This will help reduce the function's duration after the table analysis is completed.

The analysis duration is stable:

mysql> analyze table sbtest111.sbtest2;
Query OK, 0 rows affected, 10 warnings (6.22 sec)

mysql> analyze table sbtest111.sbtest2;
Query OK, 0 rows affected, 10 warnings (6.74 sec)

mysql> analyze table sbtest111.sbtest2;
Query OK, 0 rows affected, 10 warnings (6.12 sec)

What changed and how does it work?
