Cannot use incubator modules

[jeffalder]

In order to use incubator modules with the gradle plugin, I have to do the following:

1. Add --add-exports from javafx.graphics and javafx.base
2. Declare explicit implementation dependencies on the libs

I cannot figure out how to make the run task consider these dependencies for the module path, so maybe there's something I'm missing.

I propose to add incubator modules to the JavaFXModule enum so they can be specified as expected:

javafx {
    version = "25-ea+18"
    fxModules = setOf<String>("javafx.controls", "javafx.web", "jfx.incubator.richtext", "jfx.incubator.input")
}

Once this works, module-path and add-modules work, and I can modularize my application.

(Note 1: the module-info.java for richtext declares a dependency on the input module but the POM for it does not. I submitted a report to JBS but I don't see it yet.)

(Note 2: the incubator modules are "available" in JavaFX 24 but they are not published; see https://bugs.openjdk.org/browse/JDK-8354462)

I have a patch ready to start reviewing if you're interested.
