Provide test coverage for @Priority used on a stereotype

[manovotn]

Provided jakartaee/cdi#495 gets accepted, we will need test coverage for it.

Namely we need tests that:

• Use @Stereotype with @Priority to enable interceptor
• Use @Stereotype with @Priority to enable decorator (Full only!)
• Use @Stereotype with @Priority to enable alternative
• Have a @Alternative bean declaring two stereotypes both of which have @Priority and the bean itself doesn't declare @Priority
• Have a @Alternative bean declaring two stereotypes both of which have @Priority and the bean itself does declare @Priority
• Transitive stereotype scenario (stereotypes declaring stereotypes) where all stereotypes declare @Priority and assertion that the most specific value is taken
• ??

EDIT: TCKs should only cover the case of @Stereotype with @Priority used to enable alternatives as that is the main goal of this addition.
