IMPALA-15158: Replace ColumnType.is_binary_ with an enum
This is preparation for adding new types that piggy-back
on STRING (GEOMETRY/GEOGRAPHY). The new types will be
available only in Parquet, so adding the actual types
later should not need to modify unrelated file formats.

> ColumnType::is_binary_ is used to avoid creating a new type for BINARY in the
> backend - it piggy backs most of the time on STRING, and only a few places
> need to check whether it is BINARY or STRING. The same mechanism could be
> used for GEOMETRY (and GEOGRAPHY), which will be clearer if the bool is
> replaced with an enum about the logical type the array represents.
