[NETSHELL][SHELL32] Make NetShell PIDL format more Windows compatible (#7183)
- The PIDL format needs to be Windows compatible so that wlanwiz can get the
connection GUID.
- SHELL32::ILIsEqual cannot deem PIDL formats it does not understand as invalid.
- DefView must ask the folder when comparing PIDLs.
