glaveSnapshot: snapshot now does deep copy of DEVICE_CREATE_INFO struct.

* Add new local methods to do a deep copy of the DEVICE_CREATE_INFO struct. A similar method is added to do a deep free of the struct. This is just to experiment with what will be needed to support all the Create* entrypoints; most of this should be code-gen'ed later on.
* The CreateInfo struct is now also printed as part of glvSnapshotPrintDelta to confirm that it is working via the UI. Note the helper function I'm using to print the struct will only print the first layer in the list. It doesn't support printing > 1 layer.
