SID_TOGGLE_MENUBAR (aka slot:6661, .uno:MenuBarVisible) is dead

...since introduction of XLayoutManager's private:resource/menubar/menubar in
3fb2acf5b77bff59909f616c44c7de17048b64d7 "INTEGRATION: CWS layoutmanager
(1.52.10); FILE MERGED" etc. and final removal of SID_TOGGLE_MENUBAR bits in
f605b16e395e8ccc3d1aba7907b0792039016f69 "INTEGRATION: CWS sfxcleanup (1.119.8);
FILE MERGED" etc.

What still needs fixing are

  extensions/source/activex/SOActiveX.cxx
  odk/examples/DevelopersGuide/OfficeDev/DesktopEnvironment/CustomizeView.java
  odk/examples/OLE/activex/SOActiveX.cpp

in a similar way as e.g. 0273d3d81d29d5c1f6c387cca633cd99722c100e "INTEGRATION:
CWS jl18 (1.6.8); FILE MERGED."
