And remove some duplicate includes.

Discovered while investigating Bug 56551.

Previously, SetupDiGetINFClassW read INF files with
GetPrivateProfileString, which does not substitute %strkey% tokens.

This caused device installation to fail for devices which had driver
INF files using %strkey% tokens in Version section.

An example of such device is Vernier LabQuest Mini (08f7:0008) for
which Vernier's LoggerPro application includes a driver.

The INF file in question adds a new device setup class and has
following entries in Version section:

  Class = %ClassName%
  ClassGuid = %DeviceClassGUID%

Strings section includes following entries:

  DeviceClassGUID = "{6B8429BF-10AD-4b66-9FBA-2FE72B891721}"
  ClassName = "VST_WinUSB"

Previously, when LoggerPro was installed and LabQuest Mini was
hotplugged, device installation failed with the following error:

  fixme:setupapi:SetupDiGetINFClassW failed to convert "L"%DeviceClassGUID"" into a guid

This caused GUID_NULL to be used and Class was not set to the registry
for the device.

This patch fixes a regression in comparison with SLTG generator in wine-staging,
and allows oleview.exe from PSDK correctly load SLTG typelib generated by widl.

Motor City Online apparently checks for a debugger by setting this flag and then
intentionally causing a page fault. If no debugger is present on Windows, the
subprocess simply dies without spawning any crash dialog. This patch emulates
that behaviour, suppressing a (harmless) crash dialog from winedbg.

This may result in legitimate failures no longer triggering a winedbg crash
dialog, if other programs happen to use SEM_NOGPFAULTERRORBOX, but the winedbg
crash dialog cannot be relied upon anyway.

And to destroy, it'll be useful later.

It's not available on Win7.
