[CLASSPNP] Import Microsoft SCSI class driver from GitHub The source code is licensed under MS-PL license, taken from Windows Driver Samples repository (https://github.com/microsoft/Windows-driver-samples/tree/master/storage/class/classpnp/) Synched with commit 88541f70c4273ecd30c8c7c72135bc038a00fd88 The driver is written for Windows 8+, so we compile it with ntoskrnl_vista statically linked and with NTDDI_WIN8 defined CORE-17129
