[SPARK-16516][SQL] Support for pushing down filters for decimal and
timestamp types in ORC
## What changes were proposed in this pull request?
It seems ORC supports all the types in
([`PredicateLeaf.Type`](https://github.com/apache/hive/blob/e085b7e9bd059d91aaf013df0db4d71dca90ec6f/storage-api/src/java/org/apache/hadoop/hive/ql/io/sarg/PredicateLeaf.java#L50-L56))
which includes timestamp types and decimal types.
In more details, the types listed in
[`SearchArgumentImpl.boxLiteral()`](https://github.com/apache/hive/blob/branch-1.2/ql/src/java/org/apache/hadoop/hive/ql/io/sarg/SearchArgumentImpl.java#L1068-L1093)
can be used as filter value.
## How was this patch tested?
Unit tests in `OrcFilterSuite` and `OrcQuerySuite`
