tdf#93837 Never hide clipboard functions in context menus

This updates the hack made for tdf#86850 for the new
implementation. We're going to use .uno command names,
instead of sfx2 SIDs.

While touching this, I removed the check for the Paste
Special menu. It's not backed by a real sfx2 slot, so
never disabled.
