[idd] win32: use wait result constants

Use the documented Win32 wait constants throughout the pipe, clipboard,
and input workers instead of local numeric aliases.

Select the WDK NT-status definitions before including Windows headers.
Include wudfwdm.h privately in the affected translation units so UMDF 2
provides NTSTATUS without exposing WDF headers through LGCommon's public
interface to the desktop Helper.
