Ability to specify XInput DeviceSubType for Control Schemes

[mdsitton]

I am a developer of a popular rhythm game Clone Hero, and we are investigating switching to the new input system however we need support for XInput DeviceSubType for ControlSchemes to be able to differentiate the guitar controllers from normal xinput gamepads.

Add this somewhere in your startup (e.g. in some InitializeOnLoad code)

InputSystem.RegisterLayout(@"
    {
        ""name"" : ""Guitar"",
        ""extend"" : ""XInputControllerWindows"",
        ""device"" : {
            ""interface"" : ""XInput"",
            ""capabilities"" : [ { ""path"" : ""subType"", ""value"" : ""6"" } ]
        }
    }
");

This should do the trick. There should be a new "Guitar" layout under XInputController in the control picker. Let me know how it goes.
