Support the orientation lock for Tizen 2.4 compatibility.

Support the orientation lock for Tizen 2.4 compatibility.

In Tizen 2.4 WebKit locking screen orientation was possible with WebAPI
screen.lockOrientation(). This WebAPI was deprecated and replaced with
screen.orientation.lock(). But for compatibility case Web Engine needs to support
old API.
So WRT also need to support the orientation lock for backward compatibility.
