Fluid: Potential fix for T74559: Adaptive Domain creates lines in smoke 

This commit corrects the maximum resolution field in Fluid objects. The field should be set to the maximum possible resolution, i.e. it should not adjust with adaptive domains and stay constant all the time.

The reason for this is that this resolution value will be used to scale gravity. And this gravity should be constant for adaptive domains too.

It remains to be shown if this issue was the only reason for line-artifacts as seen in T74559.
