Optimize Intel SMBus Detection

Change Content

1. Query conditions of Win32_PnPSignedDriver.
2. Determination rules for the manufacturer of the SMBus controller.

Reasons for Change

1. The Description of SMBus controller may be empty (for example, motherboard: ASUS TX GAMING B760-BTF WIFI). But its DeviceName may contain "SMBus".
2. The Manufacturer of SMBus controller may be empty as well. Analyzing existing code, one boards seems to have a couple of SMBus from different manufacturer. To ensure SMBus controllers with empty Manufacturer won't be missed and to minimize the risk of misidentification, I added such a case:

IF
   the Manufacturer of SMBus controller is empty
   AND the Manufacturer of processor is Intel
   AND there is only one SMBus controller queried from WMI
THEN
   the Manufacturer of the unique SMBus controller should be Intel
END

Testing

The program has been tested on my computer and functions as expected.
