Add support for InjectionPoint with AOT

This commit reviews BeanInstanceSupplier to reuse more code from
ConstructorResolver. Previously, the autowired argument resolution was
partially duplicated and this commit introduces a new common path via
RegisteredBean#resolveAutowiredArgument.

Closes gh-30401
