gatorsmile b9eafcb526 [SPARK-31088][SQL] Add back HiveContext and createExternalTable
### What changes were proposed in this pull request?
Based on the discussion in the mailing list [[Proposal] Modification to Spark's Semantic Versioning Policy](http://apache-spark-developers-list.1001551.n3.nabble.com/Proposal-Modification-to-Spark-s-Semantic-Versioning-Policy-td28938.html) , this PR is to add back the following APIs whose maintenance cost are relatively small.

- HiveContext
- createExternalTable APIs

### Why are the changes needed?

Avoid breaking the APIs that are commonly used.

### Does this PR introduce any user-facing change?
Adding back the APIs that were removed in 3.0 branch does not introduce the user-facing changes, because Spark 3.0 has not been released.

### How was this patch tested?

add a new test suite for createExternalTable APIs.

Closes #27815 from gatorsmile/addAPIsBack.
