Register native hints for jakarta.inject annotations

Prior to this commit, native images would dynamically check for the
presence of `jakarta.inject.*` annotations and might fail at runtime or
miss them entirely.

This change ensures that if such classes are present during the AOT
build, relevant runtime hints are registered so that these annotations
can be read at runtime.

Closes gh-28614
