RFR: 8267133: jdk/jfr/event/gc/collection/TestG1ParallelPhases.java fails with Not expected phases: RestorePreservedMarks, RemoveSelfForwardingPtr: expected true, was false

[Albert Mingkun Yang]

`RestorePreservedMarks`, and `RemoveSelfForwardingPtr` are conditionally emitted (only on evac failure). Updating the test to exclude these events in the assert.


double G1GCPhaseTimes::print_post_evacuate_collection_set() const {
  ...
  debug_phase(_gc_par_phases[RecalculateUsed], 1);
  if (G1CollectedHeap::heap()->evacuation_failed()) {
    debug_phase(_gc_par_phases[RemoveSelfForwardingPtr], 1);
  }

  debug_time("Post Evacuate Cleanup 2", _cur_post_evacuate_cleanup_2_time_ms);
  if (G1CollectedHeap::heap()->evacuation_failed()) {
    debug_phase(_gc_par_phases[RecalculateUsed], 1);
    debug_phase(_gc_par_phases[RestorePreservedMarks], 1);
  }
  ...
}


Tested: manually set a smaller heap size to see the test fail, but pass with the PR.
