I'm not sure we need these. But if we do we will need it for content shell and
test shell as well. I'm not saying we need to fix it together with this patch
though. Btw ContentView/ContentViewCore onPause/onResume was intentinally
removed at some point (I don't have the rev number now but I was looking at it).
The idea was that onShow and onHide should be enough. I'm not sure this was a
good idea, currently onShow/onHide does not called correctly for content/test
shell, but probably we don't want to reintroduce them (although for me that's
fine).

Maybe we should skip this part for now?

I also questioned whether we need to reproduce onPause/Resume for GamePad, any
obvious benefit on this? Due to performance? 
Agree to skip this part as we have another CL to discuss the issue.
