Fix [#20419] OSX Cocoa physical punctuation keys retrieval fix

Browse Source 
Cocoa charactersIgnoringModifiers API still takes the Shift key into account. Fix is to use Apple new 10.5 Carbon(!) API that is 64bit compatible to take into account the international keyboard layout when retrieving the physical key pressed/released.
Needed to use an even older API for 10.4 builds.
