This adds a pipeline aggregation that calculates the cumulative cardinality of a field. It does this by iteratively merging in the HLL sketch from consecutive buckets and emitting the cardinality up to that point. This is useful for things like finding the total "new" users that have visited a website (as opposed to "repeat" visitors). This is a Basic+ aggregation and adds a new Data Science plugin to house it and future advanced analytics/data science aggregations.

Backport of #43661. The de-Guicing of xpack feature usage made the backport non-negligible, so I'm putting this up for some rounds of CI just to be safe :)
