Spring Add support for providing JNI runtime hints

This commit adds support generating graalvm jni-config.json file.

Configuration format for jni/reflection in graalvm is documented to be exactly same so we can re-use facilities for reflection hints which should be relatively clean for a user as also graalvm uses same classes for both jni/reflection.

Closes gh-29007
