[Java][MicroProfile] Use jsonb imports for serializing and deserializing enum

[Ravisankar-Challa]

Fixes the issue no: 2 reported in the issue #6028

The pull request removes all jaxb (xml) imports when withXml=false also it uses JsonbTypeSerializer & JsonbTypeDeserializer to deal with enum data types.

@Ravisankar-Challa thanks for the PR. I did a test with petstore and withXml set to true but got the following error messages (partial):

I wonder if you can take a look when you've time.

@wing328 I have fixed the issue related to withXml=true. I am able to successfully run ./bin/run-all-petstore in local. But it is failing in CI with error ./bin/run-all-petstore not found. Can you please take a look. https://cloud.drone.io/OpenAPITools/openapi-generator/9162

Please merge the latest master into your branch as we've introduced a new way to update the sample:
