As discussed in blink-dev mailing list remove getPropertyShorthand and isImplicit from the Web exposed APIs.

They were added because of the Inspector back in 2005 when it was using JS.
It does not remove the actual C++ implementation as this one is still used by
the inspector.

I've updated few layout tests to remove the usage of these functions.
