FilterInvocation Support Default Methods on HttpServletRequest

[rwinch]

FilterInvocation creates a dummy HttpServletRequest to allow creating dummy HttpServletRequest instances. The DummyRequest should support invoking default methods to support spring-projects/spring-framework#25100

Without these changes we will see stack traces that look similar to:
