[NO ISSUE][FUN] Add ARRAY_AGG() SQL aggregate function
- user model changes: yes
- storage format changes: no
- interface changes: no
Details:
- Implement support for ARRAY_AGG() aggregate function.
- Add new testcases and update documentation
- Add AbstractScalarDistinctAggregateDescriptor.createDescriptorFactory()
to uniformly set required type inferer for all distinct scalar aggregates
- Propagate correct item type to GenericScalarDistinctAggregateFunction

DISTINCT modifier is also supported for these aggregate functions.
