In the previous PR the full implementation of the $minMaxScaler window function was introduces (covering both removable and non-removable implementations). 

This PR was large and complex enough, and defers implementing the memory tracking into this ticket for simplicity.

You can search for the ticket number in the 'mongo' repo to see where the memory tracker should be added in

Note: there is no risk of releasing something that does not properly track memory before this ticket, because the $minMaxScaler window function is gated by a disabled feature flag. This break out is just for implementation and review ease
