[SPARK-43859][SQL] Override toString in LateralColumnAliasReference
### What changes were proposed in this pull request?
This PR makes it override `toString` in `LateralColumnAliasReference`.
### Why are the changes needed?
Improve the readability of logical plans.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
Manual test:
```sql
select id + 1 as a1, a1 + 2 as a3 from range(10);
```
Before this PR:
```
Project [(id#2L + 1) AS a1#0, (lateralAliasReference('a1, a1, 'a1) + 2) AS
a3#1]
+- Range (0, 10, step=1, splits=None)
```
After this PR:
```
Project [(id#2L + 1) AS a1#0, (lateralAliasReference(a1) + 2) AS a3#1]
+- Range (0, 10, step=1, splits=None)
```
Closes #41359 from wangyum/SPARK-43859.
