cros: Turn immersive fullscreen on by default

cros: Turn immersive fullscreen on by default

Use enabled/disabled flags as this will allow us to turn it off by default
after a branch point without changing the strings for about:flags.

BUG=233329
TEST=manual, toggle the option in about:flags, by default F4 should enter fullscreen
TBR=sky@chromium.org for trivial test expectation change in c/b/ui/browser_browsertest.cc
