[SPARK-20682][SQL] Implement new ORC data source based on Apache ORC
## What changes were proposed in this pull request?
Since #17924, #17943, and #17980 are a little large PRs, this is a
minimized version for next review excluding the followings. This PR still
include #18640. I will rebase after #18640 is merged.
- `OrcReadBenchmark.scala`
- `OrcColumnarBatchReader.scala`
- New ORC Test suites in `sql/core`
This PR shows new ORC datasource replaces the old ORC datasource
completely. After review, I will remove the change on old ORC datasource. We
will allow to choose one of them in #17980 .
## How was this patch tested?
Pass the Jenkins.
