D7510: windows: suppress pytype warnings for Windows imports and functions

  I'm not sure if there are plans to vendor *.pyi files.  Maybe that could be used to backfill platform specific modules instead of doing this.  But for now is seems better to get the error count and blacklist length reduced.
