[GR-53670] Layered HelloWorld

[graalvmbot]

The image heap of the application layer is now written after the image heap of the base layer. This allow to use constants from the application layer, such as the options, or the String in System.out.print. This caused the cast class error as SubstrateOptions.DumpHeapAndExit is a constant from the application layer.

The methods from the base layer need to be inlined to directly call the main method instead of going through the method handle. Note that allowing the methods from the base layer to be inlined means their graph is parsed a second time in the application layer. We do not want this, but ultimately, the graph should be persisted from the base layer. Executing the method handle currently causes a segfault with the following stack trace:

This is likely to be caused by the runtime metadata not being accessible in the application at the moment.
