Start the application myself for @NativeImageTest

[andrejpetras]

Description
I want to start the application myself for the integration tests. For example using the TestContainers framework.

Implementation ideas
Our delivery is Linux base docker image + native image. On the Windows (also on Linux) it is "hard" to test the native image.
I want to use the TestContainers for the integration test and for this I would like to have custom NativeImageLauncher.

We can use ServiceLoader and have a custom implementation of the NativeImageLauncher.

Line 57 in 49964c7

NativeImageLauncher launcher = new NativeImageLauncher(extensionContext.getRequiredTestClass());

The use case you mention where you want to start the built container should be covered by #15227
