VR: Daydream Home launch Samsung device support

This CL adds support for the S8/S9 running O, which no longer change
resolution when entering VR.

However, the user can still change resolution manually and Chrome could
end up in the wrong resolution when launched from Daydream, so we handle
this case by just killing the process and returning to Daydream, so that
when Chrome is re-launched it's launched into the correct density. It
turned out to be way too difficult to properly support Activity
recreation while avoiding showing 2D UI to users.
