[WIP] [GR-70301] Add GitHub action for weekly -H:Preserve=all testing

[graalvmbot]

In this PR we introduce weekly native image -H:Preserve=all tests to the graal GitHub actions. These tests aim to verify that images that depend on popular maven libraries can be built when preserving everything on the classpath.

The image build that the tests perform contains all of the transitive compile, runtime and provided scope dependencies (including optional dependencies) of the tested library on the classpath and use an empty DummyMain as the image entry point. If an image build fails with a --initialize-at-build-time error, the test will fetch the error-message-suggested --initialize-at-build-time argument and re-attempt the build, repeating this until either the build finishes successfully, or a different error occurs.
