[SPARK-24971][SQL] remove SupportsDeprecatedScanRow
## What changes were proposed in this pull request?
This is a follow up of https://github.com/apache/spark/pull/21118 .
In https://github.com/apache/spark/pull/21118 we added
`SupportsDeprecatedScanRow`. Ideally data source should produce `InternalRow`
instead of `Row` for better performance. We should remove
`SupportsDeprecatedScanRow` and encourage data sources to produce
`InternalRow`, which is also very easy to build.
## How was this patch tested?
existing tests.
