Check Users ID in namespace while deciding paid seat

What does this MR do?

A users is using a paid seat is defined in a Group by the highest permission the user has within the Group and not globally.

For EX:- For 2 parent Groups present in Gitlab.com Group A and Group B If a user U is a Guest in a gold plan Group A and a developer in Group B the user U is shown with a badge "Is using seat" in Group A even though he is not using the seat.

This MR checks whether the user is being billed as a paid user or not by checking the user_ids the namespace is counting it be billed.

This data comes from this MR !22967 (merged) which adds a lot of checks to get the correct count of users id to be counted
