Add Physical Presence Check and Window Open Features

This commit does the following:
- Adds an interface to detect if physical presence has been asserted
-- This happens in istep 6
-- If the window is open to detect this, it is then closed here
- Adds an interface to possibly open the window to look for physical presence
-- This happens in istep 10
-- It first checks to see if the window should be opened
-- If the window is opened then the system shuts down to wait for
   physical presence to be asserted on the next power on
- Adds the necessary attributes to support and test this functionality
