planner: fix wrong behavior for = all() (#52801)

[ti-chi-bot]

This is an automated cherry-pick of #52801

What problem does this PR solve?

Issue Number: close #52755

Problem Summary:

What changed and how does it work?

Use max function instead of first_row function.

if the query is t.id = all (select s.id from s), it will be rewrote to
t.id = (select s.id from s having count(distinct s.id) <= 1 and [all checker]) .

If there is NULL in the s.id column, s.id should be the value that isn't null in condition t.id == s.id. So use function max to filter NULL.
