[JavaJaxRS] [CXF] Add Support for Jackson3 fixes #23616

PR checklist

• Read the contribution guidelines.
• Pull Request title clearly describes the work in the pull request and Pull Request description provides details about how to validate the work. Missing information here may result in delayed response from the community.
• Run the following to build the project and update samples:

  ./mvnw clean package || exit
  ./bin/generate-samples.sh ./bin/configs/*.yaml || exit
  ./bin/utils/export_docs_generators.sh || exit
  

  (For Windows users, please run the script in WSL)
  Commit all changed files.
  This is important, as CI jobs will verify all generator outputs of your HEAD commit as it would merge with master.
  These must match the expectations made by your contribution.
  You may regenerate an individual generator by passing the relevant config(s) as an argument to the script, for example ./bin/generate-samples.sh bin/configs/java*.
  IMPORTANT: Do NOT purge/delete any folders/files (e.g. tests) when regenerating the samples as manually written tests may be removed.
• File the PR against the correct branch: master (upcoming 7.x.0 minor release - breaking changes with fallbacks), 8.0.x (breaking changes without fallbacks)
• If your PR solves a reported issue, reference it using GitHub's linking syntax (e.g., having "fixes #123" present in the PR description)
• If your PR is targeting a particular programming language, @mention the technical committee members, so they are more likely to review the pull request.

Summary by cubic

Adds Jackson 3 support to the Java JAX-RS CXF client generator via a new useJackson3 option. When enabled, it uses tools.jackson packages, the Jakarta RS provider, CXF 4.2.0, and Java 11; Jackson 2 with Java 8 remains the default.

• New Features

  • Added useJackson3; sets jacksonPackage to tools.jackson (v3) or com.fasterxml.jackson (v2).
  • POM and imports use {{jacksonPackage}}; selects jackson-jaxrs 3.1.2 + CXF 4.2.0 for v3, else 2.17.1 + CXF 3.5.9.
  • Provider imports: v3 uses ...jakarta.rs...; v2 uses ...jakarta.rs... only when useJakartaEe is true, otherwise com.fasterxml.jackson.jaxrs.
  • Java 11 for v3, Java 8 for v2; skip jackson-datatype-jsr310 when useJackson3.

• Migration

  • Set additionalProperties useJackson3: "true" (and useJakartaEe: "true").
  • Requires Java 11 when using Jackson 3.
  • For Java Time with Jackson 3, add the module explicitly in your project.
