[hpoussin] 16713: Don't compare GUID strings with wcsicmp, but compare GUID* with IsEqualIID

Don't compare GUID strings with wcsicmp, but compare GUID* with
IsEqualIID
Directly use HKEY_LOCAL_MACHINE instead of
RegOpenKey(HKEY_LOCAL_MACHINE, NULL, ...).
Remove use of UNICODE_NULL
Replace #ifdef __WINE__ by #ifdef __WINESRC__
Fix SetupDiCallClassInstaller prototype (DWORD -> DI_FUNCTION)

Thanks Usurp for your testing on Wine!

This file works now unmodified in Wine. A patch would be soon sent to
wine-patches ML.
