Fix T72253: Mantaflow adaptive domain cuts off

The issue of T72253 was that the density threshold (RNA adapt_threshold) was considering cells as empty cells too early and thus also shrinking the domain too early. The fix for this is to use smaller threshold values for the adaptive domain. This fix gives more flexibility in the UI to do just that.
