Fail fast if a `@Bean` method declares `@Autowired` as well

[jhoeller]

Along the lines of #31007 in 6.1, we intend to tighten @Bean processing further in 6.2: rejecting an accidental @Autowired annotation on a @Bean method, following up on #33030.

This is also similar to what we decided to do on the testing side.

• Validate that JUnit Jupiter test methods and lifecycle methods are not annotated with @Autowired #25966

Very nice and to-be-useful enhancement. Thanks for thinking upon and starting it, @jhoeller .
