[SPARK-16983][SQL] Add `prettyName` for row_number, dense_rank, percent_rank, cume_dist
## What changes were proposed in this pull request?
Currently, two-word window functions like `row_number`, `dense_rank`, `percent_rank`, and `cume_dist` are expressed without `_` in error messages. We had better show the correct names.
**Before**
```scala
scala> sql("select row_number()").show
java.lang.UnsupportedOperationException: Cannot evaluate expression: rownumber()
```
**After**
```scala
scala> sql("select row_number()").show
java.lang.UnsupportedOperationException: Cannot evaluate expression: row_number()
```
## How was this patch tested?
Pass the Jenkins and manual.
