Apply consistent ordering in hierarchical contexts

Previously, if `@Order` is specified on a `@Bean` method, and the
candidate bean is defined in a parent context, its order wasn't taken
into account when retrieving the bean from a child context.

This commit makes sure the metadata of a bean is taken into
consideration in all cases.

Closes gh-29105
