hyperv: recognize array property as distinct type.

hyperv: recognize array property as distinct type.

When hyperv code generator for WMI classes identifies common
properties, it needs to take into account array type as a distinct
type, i.e string != string[]. This is the case where v1 of the
Msvm_VirtualSystemSettingData has Notes property as string whereas v2
uses Notes[], therefore they have to be treated as different fields and
cannot be placed in the "common" struct.
