JClouds does not work with Jakarta XML bind on classpath

This is kind-of a follow up to JCLOUDS-1627:

When you have Spring Boot 3.2 powered environment/classpath, JClouds will fail to start with java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException.

The issue basically stems from https://github.com/apache/jclouds/blob/master/core/src/main/java/org/jclouds/xml/internal/JAXBParser.java, which is still pointing to javax.xml.bind classes.

The most simplistic solution probably would be to just replace the package names with jakarta.xml.bind.

However, if you want to continue supporting javax.xml.bind, a possible solution would be to have two different XMLParser implementations and then load either of them, depending on which JAXB variant is available on the classpath.

For reference, I have created a simple demo application that showcases the problem: https://github.com/philippn/jclouds-vs-jakarta-xml-bind

Thanks in advance for looking into it!
