Curves: Add initial undo system

Browse Source 
This adds an `UndoType` for the `Curves` object, for edit mode.
For now, this will only store the `CurvesGeometry` at every step.
Other properties such as the `selection_domain` or the `surface` object
will have to be dealt with in subsequent commits.
