Could you show a plan with multiple common table expressions? |

### What changes were proposed in this pull request?
Currently, when CTE is used in RunnableCommand, the Analyzer does not replace the logical node `With`. The child plan of RunnableCommand is not resolved. Thus, the output of the `With` plan node looks very confusing.
For example,
```
sql(
"""
|CREATE VIEW cte_view AS
|WITH w AS (SELECT 1 AS n), cte1 (select 2), cte2 as (select 3)
|SELECT n FROM w
""".stripMargin).explain()
```
The output is like
```
ExecutedCommand
+- CreateViewCommand `cte_view`, WITH w AS (SELECT 1 AS n), cte1 (select 2), cte2 as (select 3)
SELECT n FROM w, false, false, PersistedView
+- 'With [(w,SubqueryAlias w
+- Project [1 AS n#16]
+- OneRowRelation$
), (cte1,'SubqueryAlias cte1
+- 'Project [unresolvedalias(2, None)]
+- OneRowRelation$
), (cte2,'SubqueryAlias cte2
+- 'Project [unresolvedalias(3, None)]
+- OneRowRelation$
)]
+- 'Project ['n]
+- 'UnresolvedRelation `w`
```
After the fix, the output is as shown below.
```
ExecutedCommand
+- CreateViewCommand `cte_view`, WITH w AS (SELECT 1 AS n), cte1 (select 2), cte2 as (select 3)
SELECT n FROM w, false, false, PersistedView
+- CTE [w, cte1, cte2]
: :- SubqueryAlias w
: : +- Project [1 AS n#16]
: : +- OneRowRelation$
: :- 'SubqueryAlias cte1
: : +- 'Project [unresolvedalias(2, None)]
: : +- OneRowRelation$
: +- 'SubqueryAlias cte2
: +- 'Project [unresolvedalias(3, None)]
: +- OneRowRelation$
+- 'Project ['n]
+- 'UnresolvedRelation `w`
```
BTW, this PR also fixes the output of the view type.
