[CDROM][CLASS2][DISK] Remove the old class drivers stack
These drivers are based on NT4 DDK sample code, were originally
started by Alexey Bragin and then constantly patched by Pierre
Schweitzer to fix compatibility with NT5+ storage stack.
Replaced with Microsoft drivers published on GitHub by an open
license.
These drivers were originally added as part of
