[C++][Compute] Implement count distinct kernel using HyperLogLog

[asfimport]

Having a version of the aggregation kernel count distinct using HyperLogLog may be useful.

Note: The implementation should support the merge operator.

ZMZ91 / @ZMZ91: hi there, is this feature on schedule?

[asfimport]

Dhruv Vats / @dhruv9vats: Is there still interest in this? If so, I'd be happy to give this a go.

Also, this will go into {}hash_aggregate{}, right? And could be named something like hash_count_distinct_estimate or {}hash_count_distinct_hll{}?

[asfimport]

ZMZ91 / @ZMZ91: Sure. We'd like to have a hash_count_distinct_hll for a proximate result in many real cases.
