[4947][java]: adds support for validation of primitives in arrays (#17165)

* [4947][java]: adds support for validation of primitives in arrays

* [4947][java]: prevents generation '@Valid' for Object

* [4947][java]: test against different codegens and stick to primitive

* [4947][java]: code review

* [4947][java]: enhance getBeanValidation

* [4947][java]: adds email

* [4947][java]: removes unnecessary override

* [4947][java]: adds postProcessResponseWithProperty

* [4947][java]: adds missing import {{javaxPackage}}.validation.Valid

* [4947][java]: adds missing useBeanValidation

* [4947][java]: fix use rootJavaEEPackage for helidon
