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

[pabulaner]

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 the registration takes place inside the start method of an application before calling the show method.

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.
