False color, need quicker access

I believe it would be useful to be able to setup two 3dViewport editors side to side, one with false color on while the other one having "normal" colors.

However currently false color is only available through props.render.colorManagement.viewTransform, and it affects every viewport.

So it would be cool to have a way for each viewport to have its own falseColor toggle, or at least to have the possibility to add the props.render.colorManagement.viewTransform menu in the quick favorites so that we can switch quickly between falseColor and regular mode.
