cmState: Move snapshot creation to the cmake instance.
Don't create a snapshot in Initialize(), but leave the creation responsibility to the cmake instance instead. Previously, the cmState would Initialize() in its constructor, and the cmake instance would re-Initialize() during Configure(). The end result was the same and there would be one snapshot present. However, cmLocalGenerator also created a snapshot on construction, and that one was used, leaving the first snapshot unused, and potential for off-by-one errors. Fix that by making the cmLocalGenerator use the existing snapshot if it is top-level. Add a CurrentSnapshot to the cmake instance and populated it while configuring a directory. This will eventually replace the 'current local generator' concept. Fix the GetParent implementation to be able to return the first snapshot.
