undo: set dive mode to CCR in undo command, not profile code

When setting a CCR setpoint, the profile code(!) would turn
the dive into a CCR dive. Not only should the display layer
not alter dives, this also means that the action is not
undoable.

Move that to the appropriate undo command, where it makes
more sense, but obviously also makes things more complicated.
