dinput: Implement HID joystick IDirectInputDevice8_SetProperty.

For DIPROP_RANGE property on POVs and Axes, and initialize it on
creation.

This uses the value caps physical range, as it's exactly the purpose and
we don't use it for anything else otherwise.

We'll scale values from their logical range directly anyway to save a
conversion.
