Hibernate Validator: Consider all superclasses when checking for annotations and add tests

[famod]

Description
In #11506 (which had another/smaller scope initially) I extended the transformer to look for validation and/or JAX-RS annotations also in the direct superclass.
Theoretically, this is an incomplete solution - the entire hierarchy has to be checked instead.
#11506 did also not add any superclass tests.

Update, idea from @gsmet (discussed via private messages on Zulip):

you would do everything in the processor
by registering keys for the subclasses/implementations
going down the hierarchy in the processor
instead of having to go up in the transformer
