Cursors are broken on Windows
Starting with 45.0 the cursors are installed into a wrong directory, "share/icons/Adwaita/Adwaita/cursors" instead of "share/icons/Adwaita/cursors".
Fixing that still doesn't make most of them work in gtk3-demo/gtk4-demo though. Comparing the list of installed cursors, about half of them are missing now compared to 44.0.
