Add Jakarta-variant of "JAXB" annotations: `jackson-module-jakarta-xmlbind-annotations`

[cowtowncoder]

So, with Javax->Jakarta developments wherein JAXB api is now forked hard, we have an attempted workaround of using classifier "jakarta", publishing 2 jar variants.
But this seems to have issues at least wrt OSGi; so maybe we better bite the bullet, create 2nd module with copied code but covering Jakarta variant of XML binding API.

Also see my question on what to call "new" JAXB:

jakartaee/jaxb-api#179

This would be for Jackson 2.13. Trade-off as I see it:

• CON: More code to maintain for now -- possibly not for 3.0 (if we only migrate new variant)
• PRO: Known to work: 2 different artifacts, simple dependencies, no post-processing

Added new variant:

• Sub-folder: jakarta-xmlbind
• Maven coordinates:
  • Artifactjackson-module-jakarta-xmlbind-annotations (group id com.fasterxml.jackson.module)
• Java package: com.fasterxml.jackson.module.jakarta.xmlbind
• Module id: com.fasterxml.jackson.module.jakarta.xmlbind (same as Java package)
• Module name: JakartaXmlBindAnnotationModule

cc @GedMarc I think that due to complications with dependencies, this is the route to take. Work so far:

1. Remove JAXB annotations dependency from XML module (used only for tests, but not required runtime)
2. Add alternate Jakarta-XMLBind module here (help appreciated wrt metadata) -- mostly to remove now unnecessary imports from module def if necessary

And then I'll need to tackle RS side. I think jaxrs just becomes jakarta-rs from Jackson perspective; although kind of wondering if I should also try to remove JAXB annotation dependency (removed from 3.0, but tempted to drop automatic support from Jakarta/2.13 variant).
