[Java] Add missing imports for Set in java clients (#10171)

* Add missing imports for Set in microprofile client

In case of array properties declared with uniqueItems: true, the
generated Java code uses Sets but imports are not present for them in
the Api and Test classes.

* Add missing imports for Set in java native clients

In case of array properties declared with uniqueItems: true, the
generated Java code uses Sets but imports are not present for them in
the Api and Test classes.
