winexinput.sys: Introduce a new winexinput.sys driver. 

Currently only acting as a pass-through driver, matching any device with
a WINEBUS\WINE_COMP_XINPUT compatible id.

This creates new WINEXINPUT\ bus and the gamepad PDO on it, adding the
&IG_ device id suffix to the original device id (replacing an eventual
&MI_ suffix), and removes the need to set it on winebus.sys side.
