Fix missing port_undef (#20052)

unparser.cc, arenaz_sampler_test.cc, and message_module.cc included port_def.inc but forgot to include the undef file.  This can cause some issues on which absl macros are defined:

In file included from
/opt/protobuf-29/include/google/protobuf/arena.h:36: In file included from
/opt/protobuf-29/include/google/protobuf/arena_align.h:63: /opt/protobuf-29/include/google/protobuf/port_def.inc:542:5: error: function-like macro 'ABSL_HAVE_FEATURE' is not defined \#if ABSL_HAVE_FEATURE(address_sanitizer)

Closes #20052
