Polish Method Authorization Denied Handling

- Renamed @AuthorizationDeniedHandler to @HandleAuthorizationDenied
- Merged the post processor interface into MethodAuthorizationDeniedHandler , it now has two methods handleDeniedInvocation and handleDeniedInvocationResult
- @HandleAuthorizationDenied now handles AuthorizationDeniedException thrown from the method

Issue gh-14601

-=== Using with `@PostAuthorize`
+=== Using the Denied Result From the Method Invocation
 
-The same can be achieved with `@PostAuthorize`, however, since `@PostAuthorize` checks are performed after the method is invoked, we have access to the resulting value of the invocation, allowing you to provide fallback values based on the unauthorized results.
+There are some scenarios where you might want to return a secure result derived from the denied result.
+For example, if a user is not authorized to see email addresses, you might want to apply some masking on the original email address, i.e. _useremail@example.com_ would become _use\\******@example.com_.
+
+For those scenarios, you can override the `handleDeniedInvocationResult` from the `MethodAuthorizationDeniedHandler`, which has the {security-api-url}org/springframework/security/authorization/method/MethodInvocationResult.html[`MethodInvocationResult`] as an argument.
 Let's continue with the previous example, but instead of returning `null`, we will return a masked value of the email:

 === Deciding What to Return Based on Available Parameters
 
-Consider a scenario where there might be multiple mask values for different methods, it would be not so productive if we had to create a handler or post-processor for each of those methods, although it is perfectly fine to do that.

 In such cases, we can use the information passed via parameters to decide what to do.
 For example, we can create a custom `@Mask` annotation and a handler that detects that annotation to decide what mask value to return:
