Add AOT/Native support

This commit adds AOT/Native support for beans that are contributed by
the Kotlin DSL.

Since they use an instance supplier, such beans are now configured to
be ignored by AOT generation. They are part of the bean factory still
so any hint generation works.

This commit removes a previous attempt at fixing this issue when we
were not checking for instance suppliers. Rather than skipping the
initializr at runtime, it runs again as intended since their state
can't be stored in AOT-generated code.

Closes gh-29555
