Add enabling/disabling of NetworkInformation API via WebRuntimeFeatures.  This lets us restrict the API to the platforms that are fully implemented while we develop the others.

See https://codereview.chromium.org/424823002/ for the Chromium code that uses this.

DevTools: highlight page regions as paths, not quads

We used to pass a typed set of quads plus the config that specified
color for each type of quad. This is not flexible enough to cover
the needs of highlighting of different types of render objects.
This switches to a more flexible interface passing an array of paths
with fill & outline colors specified for each path.
