libpci: Add new windows kldbgdrv.sys implementation
Microsoft Kernel Local Debugging Driver (kldbgdrv.sys) allow access for
userspace processes to the PCI config space. It supports access up to
65536 domains and whole 4096 bytes long extended PCIe config space. Driver
is signed by Microsoft and is available for both 32-bit and 64-bit systems.
Driver is not part of Windows system and has to be installed via WinDbg
installation package. Standalone installers for WinDbg 6.12.2.633 version:
https://download.microsoft.com/download/A/6/A/A6AC035D-DA3F-4F0C-ADA4-37C8E5D34E3D/setup/WinSDKDebuggingTools_amd64/dbg_amd64.msi
https://download.microsoft.com/download/A/6/A/A6AC035D-DA3F-4F0C-ADA4-37C8E5D34E3D/setup/WinSDKDebuggingTools/dbg_x86.msi
This kldbgdrv.sys API is used by the !pci command of new WinDbg kernel
debugger for displaying PCI config space.
API of this driver is available only for processes with Debug privilege and
only if system was booted with Debugging option.
