Today's implementation only return key state when there is key.
But when user doesn't press any key, the key state cannot be
returned.
The patch changes the ReadKeyStrokeEx() to always return the
key state even there is no key pressed.

Hi Ruiyu,
One comment:
ConSplitterTextInPrivateReadKeyStroke() needs filter out partial key from ConSplitterTextInExDequeueKey().
With the comment above handled, Reviewed-by: Star Zeng <star.zeng@intel.com> to this patch series.
Thanks,
Star
