[SPARK-33956][SQL] Add rowCount for Range operator

### What changes were proposed in this pull request?

This pr add rowCount for `Range` operator:
```scala
spark.sql("set spark.sql.cbo.enabled=true")
spark.sql("select id from range(100)").explain("cost")
```

Before this pr:
```
== Optimized Logical Plan ==
Range (0, 100, step=1, splits=None), Statistics(sizeInBytes=800.0 B)
```

After this pr:
```
== Optimized Logical Plan ==
Range (0, 100, step=1, splits=None), Statistics(sizeInBytes=800.0 B, rowCount=100)
```

### Why are the changes needed?

 [`JoinEstimation.estimateInnerOuterJoin`](d6a68e0b67/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/plans/logical/statsEstimation/JoinEstimation.scala (L55-L156)) need the row count.

### Does this PR introduce _any_ user-facing change?

No.

### How was this patch tested?

Unit test.

Closes #30989 from wangyum/SPARK-33956.
