[NEWDEV] Fix HardwareId match logic in UpdateDriverForPlugAndPlayDevicesW (#7808)

Browse Source 
Match Hardware ID correctly. This fix is required to install the latest (7.1.6) Virtual Box Guest Additions drivers.

- Add Compatible IDs match, call SetupDiGetDeviceRegistryPropertyW twice, once for SPDRP_HARDWAREID and once for SPDRP_COMPATIBLEIDS.
- Use case-insensitive comparison (wcscmp -> _wcsicmp)
- Convert code file to UTF-8 encoding
