Target Windows 10 using its GUID. re #4760

Starting with Windows 8.1, Microsoft recommends developers to use ap manifests to specify OS compatibility instead of relying on version info tuple (which Python returns via Windows API). This was used for fixing ticket 3793 (targeting Windows 8.).
This also applies to Windows 10 in that it has its oww GUID. Without this Windows 10 tells NVDA that it is Windows 8.1 (NT6.3, not NT6.4/10.0). Thus the new GUID for Windows 10 was added to declare that NVDA supports Windows 10.
