introduce SwClient::EndListeningAll()

- this is to reduce the use of GetRegisterdIn(), which should be an
  implementation detail
- remove SwTOXMark::DeRegister() which did the same for a part of the
  class tree
- remove SwUndoSetFlyFormat::DeRegisterFromFormat(), same
- remove doubletracking FrameDeleteWatch::m_bDeleted, just check
  GetRegisteredIn()
