sw undo: add a Repair argument to the .uno:Undo/Redo commands

Undo/redo is limited to undo actions created by the same view in the LOK
case, this argument removes this limit. This can be used by a client for
"document repair" purposes, where undo/redo of others' changes is
intentional.

The sfx command dispatch has support for FASTCALL slots (a state
function is not called, the command is always enabled) and also has
support for state functions, but those functions only get the ID of the
slots, not its parameters. What is needed here is a command that's
disabled by default, but in case a Repair argument is used, then it's
unconditionally enabled. So handle that case in the sfx dispatcher
directly for now.
