[9/11]hidclass.sys: Add Plug-and-play interfaces

Thank you very much for the review here.  The Device Driver code was the area I was least confident.

Now, MUCH of the windows kernel level (KEVENT etc...) stuff is not implemented in wine and not really needed.

Thanks for the WINAPI pointer here.  The cast is needed to silence errors as currently DRIVER_EXTENSION->AddDevice is a PVOID in the header.
