[CRD iOS] Improve viewport manipulation on iPhone X

This CL allows the iOS client to display desktop that is partially
obstructed by the notch while allowing user to pan the desktop out of
the obstructed area, similar to what we have done on the Android
client.

This CL also changes the previous logic that handles keyboard height.
We are now using DesktopViewport's SetSafeInsets() methods to adjust
for the keyboard rather than just changing the surface size.

(the bar acting like a virtual home button), so that user can see
things on the bottom after the home indicator times out.

This CL is dependent on internal CL:
