Add setFocusedWindow function stub
This function, once implemented, will set focus on the specified
window. This is the first step in changing focus selection from
setInputWindows and using explicit call which will help us more
easily decouple z-order from focus selection and support focus
for SurfaceViewHost surfaces.

+ * Sets focus to the window identified by the token. This must be called

+ * Params:

+ * request.focusedToken - the token that the caller expects currently to be focused. If the
+ * specified token does not match the currently focused window, this request will be dropped.
+ * If the specified focused token matches the currently focused window, the call will succeed.
+ * Set this to "null" if this call should succeed no matter what the currently focused token is.
+ * request.timestamp - SYSTEM_TIME_MONOTONIC timestamp in nanos set by the client (wm)
+ * when requesting the focus change. This determines which request gets
+ * precedence if there is a focus change request from another source such as pointer down.
