Broken CursorIcons in native MacOS versions ~14.1 and above

[voidburn]

Creating this issue for visibility, this is not an Egui bug. (please assign the Winit label)

The following cursors are broken for all native builds on MacOS with versions above 14.1:

This can be tested by opening any fully resizable egui::Window in the demo app and attempting to resize the windows via corners -> the cursor shown will be the default one instead of the corner resize one(s).

There is currently no way to set custom cursors in Egui, so we have a situation in which there is no temporary alternative other than Winit updating their platform implementation in order to restore functionality.

Winit 0.30.6 is out now along with the fix to this issue.
