Adjust code to provide basic Android support

[lakor64]

The following code adds JAXB marshalling and unmarshalling support for Android Java runtime, as ART is implemented differently than a standard Openjdk implementation.

StackWalker is present in Android API since API Level 34 (Android 14) which approximately 50% of devices currently supports, which is why I have decided to provide an alternative implementation for older API levels (based from the previous Jakarta code before bumping to Jdk11)

Android does not provide any implementation for java.awt.*, which is why I check during runtime if this classes are present,
Android also does not provide a StaX implementation, which is why I added an extra StaX dependency found online, I belive if there is any interest to remove StaX dependency for Android it whould be done on another PR.

Android also, does not support Java 9+ modules, according to the previous code of MUtils the function was empty before switching to Jdk9, which is where I replicate such behaviour.

All maven tests passes.

Relevant code that was tested under Android:

    public static <T> void marshalRes(T req, Writer in) throws JAXBException, IOException {
        JAXBContext ctx = JAXBContext.newInstance(req.getClass());
        Marshaller m = ctx.createMarshaller();
        StringWriter w = new StringWriter();
        m.marshal(req, w);
        String p = w.toString();
        in.write(p);
    }

without this edits, JAXBContext.newInstance would crash, while on Openjdk it would work as intended.

Extra environment information for replicating marshaller/unmarshaller tests:

• Gradle: 9.1.0 /w AGP 8.13.0
• Min SDK: 24
• Max SDK: 34
• Compile SDK: 36
• Desugaring enabled with source and target version set to Java 11
• Successfully run on Android 7.1
