Remove QPropertyMemberChangeHandler again

Adding support for a static notifier within QProperty itself - through a
QProperty "sister" class - is more efficient in terms of memory
consumption and run-time performance.

The MemberChangeHandler permanently takes up at least three pointers,
while the notified properties only cost one pointer in the binding.
