[ios] Make NTP really full screen.

Short term solution to long term problem of pulling the NTP out of native content.
For now, convince //ios/web to show the NTP native content as full screen (including
under the status bar) by sending a negative offset to web when calculating the frame
of the native content.

There are differences between iOS10 and iOS 11

Is this WAI?

Not WAI!  This appears to be broken on iOS10.  I see what's wrong here, thanks for catching!
