Windows: Try alternative methods to query port number
This commit is similar to #634 but I think it offers a better approach. The commit adds two more methods for querying the port number, in addition to the existing SPDRP_ADDRESS method, which may not actually return the port number when using USB drivers other than the Microsoft driver.
The first method uses SPDRP_LOCATION_INFORMATION, which may return a port in a format similar to "Port_#0002.Hub_#000D".
The second method uses SPDRP_LOCATION_PATHS, which returns the device location in a format similar to "PCIROOT(B2)#PCI(0300)#PCI(0000)#USBROOT(0)#USB(1)#USB(2)#USBMI(3)", where the port number is the number within the last "#USB()" token.
If both methods fail, SPDRP_ADDRESS is still used as a fallback.
Closes #867
