Yesheng Ma e037a11494 [SPARK-28532][SQL] Make optimizer batch "subquery" FixedPoint(1)
## What changes were proposed in this pull request?
In the Catalyst optimizer, the batch subquery actually calls the optimizer recursively. Therefore it makes no sense to enforce idempotence on it and we change this batch to `FixedPoint(1)`.

## How was this patch tested?
Existing UTs.

Closes #25267 from yeshengm/SPARK-28532.
