### Is your feature request related to a problem or challenge?
Current source executors(`CsvExec, etc.`) contains `outpout_ordering` inside
display. For the following table
```sql
CREATE EXTERNAL TABLE multiple_ordered_table (
a0 INTEGER,
a INTEGER,
b INTEGER,
c INTEGER,
d INTEGER
)
STORED AS CSV
WITH HEADER ROW
WITH ORDER (a ASC, b ASC)
WITH ORDER (c ASC)
LOCATION '../core/tests/data/window_2.csv';
```
display would be
```sql
----CsvExec: file_groups={1 group: [[path]]}, projection=[a, b],
output_ordering=[a@0 ASC NULLS LAST, b@1 ASC NULLS LAST], has_header=true
```
It would be nice, if output ordering would contain all of the valid
orderings at the source such as following
```sql
----CsvExec: file_groups={1 group: [[path]]}, projection=[a, b],
output_orderings=[[a@0 ASC NULLS LAST, b@1 ASC NULLS LAST], [c@2 ASC NULLS
LAST]], has_header=true
```
