[SPARK-3575][SQL][WIP] Removes the Metastore Parquet conversion hack
Still a WIP.
This PR tries to remove the Metastore Parquet conversion hack by moving the
conversion logic to `HiveMetastoreCatalog`, i.e., convert `MetastoreRelation`
to `ParquetRelation` when we find that the Hive table is backed by Parquet.
Also, the converted `ParquetRelation` inherits the original Hive schema.
TODO
- [ ] Add tests
- [ ] Fix partitioning tests failure
- [ ] Remove `spark.sql.parquet.binaryAsString`
