Those can be trivially removed as they have direct replacements, or
are completely unused.
The migration path for QCursor::bitmap and QCursor::mask is
QBitmap *pb = c.bitmap(); // up to 5.15, warns in 5.15
QBitmap vb = c.bitmap(Qt::ReturnByValue); // from 5.15, works in 6
QBitmap b = c.bitmap(); // from 6.0 on
