ARROW-12673: [C++] Add callback to handle incorrect column counts

Add a new callback handler to the csv parser which is invoked when the column count in a row does not match the expected. The callback can return an enum which indicates if the row should result in an error result or it should be skipped.

Replaces https://github.com/apache/arrow/pull/10202

Closes #10790 from n3world/ARROW-12673-Invalid_column_count
