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.

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
