spapr: nested: Introduce SpaprMachineStateNested to store related info.

Browse source 
Currently, nested_ptcr is being used by existing nested-hv API to store
nested guest related info. This need to be organised to extend support
for the nested PAPR API which would need to store additional info
related to nested guests in next series of patches.
