[Driver] Add support for Windows 10 SDK 

Summary:
With Windows 10 SDK, Include and Lib directories now contain an additional subfolder with the name that corresponds to the full version of the SDK, for example:
  - C:\Program Files (x86)\Windows Kits\10\Include\10.0.10240.0\um
  - C:\Program Files (x86)\Windows Kits\10\Lib\10.0.10240.0\um\x64
