Fix corrupted cursors on Windows high-DPI and remove obsolete cursors
The biggest change is to use the QCursor(QPixmap)
constructor instead of QCursor(QBitmap, QBitmap)
. QBitmap-based cursors behaves quite broken on Windows with high-DPI scaling, so this MR ditches it.
I can consider backporting "Change image-based cursors to be loaded as QPixmap" and "Convert KoPathTool cursors to XPM" for 5.0.4, but will leave the other two.
