[SPARK-38526][SQL] Fix misleading function alias name for RuntimeReplaceable

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

This PR uses a manual recursion to replace `RuntimeReplaceable` expressions instead of `transformAllExpressionsWithPruning`. The problem of `transformAllExpressionsWithPruning` is it will automatically make the replacement expression inherit  the function alias name from the parent node, which is quite misleading. For example, `select date_part('month', c) from t`, the optimized plan in EXPLAIN before this PR is
```
Project [date_part(cast(c#18 as date)) AS date_part(month, c)#19]
+- Relation default.t[c#18] parquet
```
Now it's
```
Project [month(cast(c#9 as date)) AS date_part(month, c)#10]
+- Relation default.t[c#9] parquet
```

### Why are the changes needed?

fix misleading EXPLAIN result

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

no

### How was this patch tested?

new test
