Move QObjectBindableProperty documentation into snippet file

The \Q_OBJECT macro has been removed but using Q_OBJECT in the file
would erroneously trigger automoc. Avoid the issue by moving
the snippet into its own file.

   Use the Q_BINDABLE_PROPERTY macro in the class declaration to declare the property as bindable.

   If the property does not need a changed notification, you can leave out the "NOFITY xChanged" in the Q_PROPERTY macro as well as the last argument
   of the Q_OBJECT_BINDABLE_PROPERTY macro.
