Gabor Kaszab 63f52518ab IMPALA-8801: Date type support for ORC scanner ...

Implements read path for the date type in ORC scanner. The internal
representation of a date is an int32 meaning the number of days since
Unix epoch using proleptic Gregorian calendar.

Similarly to the Parquet implementation (IMPALA-7370) this
representation introduces an interoperability issue between Impala
and older versions of Hive (before 3.1). For more details see the
commit message of the mentioned Parquet implementation.
