rotate and perspective: scrolling up/down should increase/decrease selection circle diameter

[kofa73]

When editing drawn masks, scrolling up / down increases / decreases the size of the selection circle, the drawn mask, or feathering. In rotate and perspective, it works the other way around. The current PR applies the same behaviour as used in masks, up means increase, down means decrease.

Thanks @TurboGit , but there's more to clean up, see #20832 (comment). We'll have to discuss this and come up with a plan.

An added complication is that some enable a "natural scroll" setting, which reverses scroll direction, which they'll probably want to keep for scroll bars, but still use scroll up / down = increase / decrease size (e.g. selection circles) or value (sliders).

Yes, saw that.

We need a release note entry for 5.6. Also please check other closed PR if needed. TIA.

Fixed scroll direction in rotate and perspective module: scrolling up/down now increases/decreases the selection circle size, matching how resizing drawn masks works.
