Add more dummy methods to the Android launcher

This is a follow up to gluonhq#971 and gluonhq#972.

I made a minimal Android app with FXGL, the game engine which uses JavaFX. It turns out that GraalVM Native Image
adds many more unresolved references when compiling FXGL. I added the dummy methods for them to launcher.c.

With these changes my minimal app works  but I wonder if this is a good approach. All the methods I added have
something to do with image handling. What if, when I start to write a more complex app, GraalVM Native Image will
start adding even more references?

Here's my app: https://github.com/makingthematrix/scalaonandroid/tree/main/HelloFXGL
