Using IME context to inflate layout from S_V2

With CL[1],[2] to migrate InputMethodService as the subclass of the new
introduced class WindowProviderService in S_V2, IME context resources
can be managed by associating the window container of IME window when
its display/window configuration changed.

So we can get rid of createDisplayContext logic from S_V2 with gated
by SDK version and refining the method of get IME context with
documentation to make it clear.
