To quote the documentation:
Queries and returns the state of the modifier keys on the keyboard.
Unlike keyboardModifiers, this method returns the actual keys held
on the input device at the time of calling the method.
So GetCurrentKeyModifiers seems to be the correct Carbon
function to use.
[ChangeLog][QtGui][QGuiApplication] Fix queryKeyboardModifiers() on
macOS to actually return the current modifier key state
