InputCommon: Fix slow startup on some Windows systems

Browse Source 
Rewrite GetXInputGUIDS to use SetupAPI instead of WMI Queries. When
using a language pack where the system language and user/program
language differ, Windows starts taking a VERY long time (10+ seconds)
to complete Queries for Win32_PNPEntity objects (it's probably
translating every single string since it transfers every single one
from the WMI server into memory in the program).

Fixes Issue 9744.
