RFR: 8332947: [macos] java.awt.desktop.OpenURIHandler is not receiving events [v5]

[Pabulaner IV]

> When trying to register an open URI handler when using JavaFX with a native menu, this task fails on Mac.
> Either the native menu is not shown or the URIs are not received.
> 
> This pull request fixes this issue if AWT is registered after JavaFX, so that AWT runs embedded inside JavaFX.
> It fixes this by introducing a native event to AWT, which can be used by JavaFX to forward events such as an openURL event.
