`DefaultWebInvocationPrivilegeEvaluator` can't handle rules based on remote address

[fast-reflexes]

Describe the bug
When the ErrorPageSecurityFilter kicks in, it uses the DefaultWebInvocationPrivilegeEvaluator to determine if some error pages should be shown or if just a status code should be sent. If the pattern controlling access to error pages contain patterns based on remote address, the invocation fails with an exception:

To Reproduce

1. Download project https://github.com/fast-reflexes/spring-boot-bug/tree/getRemoteAddrNotImplemented
   It is a project with the following security config:

   override fun configure(http: HttpSecurity) {
       http
           .authorizeRequests()
           .antMatchers("/error/**").hasIpAddress("127.0.0.1")
           .antMatchers("/non-existing/**").denyAll()
           .antMatchers("/test/**", "/favicon.ico").permitAll()
           .anyRequest().denyAll()
   }
   

2. Start the app with ./gradlew bootRun

3. Access localhost:8080/non-existing

4. Check exception in console

Expected behavior
Expected behaviour is to either allow access to the Spring error page or to just send a status code, depending on the remote address pattern and remote address itself. Definitely not an exception and downgrading to the Tomcat error page.

Hi @fast-reflexes, we are investigating alternatives to the ErrorPageSecurityFilter here #10919.

I recommend you to take a look at #11055 (comment) where I provided some workaround.

I'm closing this so we can centralize the comments and effort in just one ticket. Thank you very much for the report and stay tuned to the other tickets.
