[SPARK-14213][SQL] Migrate HiveQl parsing to ANTLR4 parser [WIP]
### What changes were proposed in this pull request?
This PR migrates all HiveQl parsing to the new ANTLR4 parser. This PR is
build on top of https://github.com/apache/spark/pull/12011, and we should wait
with merging until that one is in (hence the WIP tag).
As soon as this PR is merged we can start removing much of the old parser
infrastructure.
### How was this patch tested?
Exisiting Hive unit tests.
