[SPARK-25955][TEST] Porting JSON tests for CSV functions
## What changes were proposed in this pull request?
In the PR, I propose to port existing JSON tests from `JsonFunctionsSuite`
that are applicable for CSV, and put them to `CsvFunctionsSuite`. In particular:
- roundtrip `from_csv` to `to_csv`, and `to_csv` to `from_csv`
- using `schema_of_csv` in `from_csv`
- Java API `from_csv`
- using `from_csv` and `to_csv` in exprs.
