Title: Add support for Keys.RightControl/Keys.RightShift

This is a new implementation that depends on information found at the
event status. It doesn't need CoreWindow.GetKeyState(...) as my previous commit.

We detect RightControl by checking KeyStatus.IsExtendedKey.
To detect RightShift we need to check the scancode.
