Commit Message

[BREAKING] Use DataAPI.refpool for optimized grouping (#2442)

Generalize existing optimized `row_group_slots` method for `CategoricalArray`
and `PooledArray` so that it can be used for other array types
for which `DataAPI.refpool` returns an `AbstractVector`. This allows dropping
the dependency on CategoricalArrays in this part of the code.

Also refactor the method to be faster when not sorting. In that case, we do
not need to build a map between reference codes and groups (indexing into it
is slow when the number of groups is very large). `CategoricalArray` is no longer
special cased: when `sort=false`, levels are still sorted, but `missing` appears first.

Add more tests to cover weird combinations.
