Fix incorrect cursor scaling by using autoscale zoom

Previously, custom cursors were scaled using the raw device zoom
(getNativeZoom),
which could result in mismatched sizes on high-DPI displays. This change
replaces
it with DPIUtil.getZoomForAutoscaleProperty to align cursor scaling with
the rest
of the UI.

Fixes #2308
