SI-8954 Make @deprecated{Overriding,Inheritance} aware of @deprecated.

This makes sure than:
 - there is no warning for a @deprecated class inheriting a
   @deprecatedInheritance class
 - there is no warning for a @deprecated method or a method of a
   @deprecated class overriding a @deprecatedOverriding method

This should remove quite a few useless deprecation warnings from the
library.
