[xinput] Remove use of private APIs on Windows 8/10

[garbear]

The crash on Windows 10:

INVALID_POINTER_READ_DETOURS_c0000005_XInputUap.dll!XInputCore::XInputManager::_XInputManager

This might be caused by the private API used to access the Guide button and Power-off feature. This PR disables these on Windows 10.

I can't compile on Windows ATM so this PR is untested.

Looks like M$ made quite a mess with the XInput versions and what features they provide... I didn't realize that when I implemented these advanced features.

Well, can't expect a stable interface if we're using internal methods. Seems they failed with the design of the API though if we need to resort to such trickery.

Would like to see this in ASAP as this crash is in the top 5 or even top 3 in the win store crashes

@Paxxi: From what I read they're not explicitly internal but they are only available with XInput 1.3 which only comes with the DirectX SDK (which is why it's available on developer machines).
And it looks like for Windows store apps only XInput 1.4 is supported. And the docs even say that XInput 1.4 has several disadvantages over XInput 1.3 or XInput 9.1.0.

To me that looks like quite a mess.

Do you think they are the problem? This PR is a little hacky, but we can fix later. I've compile tested on Windows so I'm going to merge this.

@Montellese no arguments about it being a mess 😀
