### What changes were proposed in this pull request?
This pr pushdown limit through InnerLike when condition is empty(Origin pr:
#23104). For example:
```sql
CREATE TABLE t1 using parquet AS SELECT id AS a, id AS b FROM range(2);
CREATE TABLE t2 using parquet AS SELECT id AS d FROM range(2);
SELECT * FROM t1 CROSS JOIN t2 ON a = d LIMIT 10
```
Before this pr:
```
== Physical Plan ==
AdaptiveSparkPlan isFinalPlan=false
+- CollectLimit 10
+- BroadcastNestedLoopJoin BuildRight, Cross
:- FileScan parquet default.t1[a#5L,b#6L] Batched: true, DataFilters:

```
