RFR: 8354631: [macos] JFX - java.awt.desktop.OpenURIHandler is not receiving events [v2]

[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.
> 
> The test for this pull request is non trivial, as the application needs to be installed on the Mac before it can be tested. Therefore the test is provided in a separate repository and it needs to be discussed if the test is necessary to have inside the JFX repo and if so, how it should be integrated.
