Fix Linux GN build after crrev.com/273992

Looks like before this change went in webkit/common/BUILD.gn was landed
and thus when crrev.com/273992 landed they conflicted.

This patch removes the resource_devtools_info.* entries from
webkit/common/BUILD.gn, since now they were moved into
content/content_common.gypi.

Client-side changes to support requesting lossless encode & color.

This adds setLosslessEncode() and setLosslessColor() calls to the
ClientPlugin API, which future updates to the app can use to request
lossless frames if desired.

Instant interactive_ui_tests should wait for main frame load.

Before this patch, instant search tests didn't wait for the main frame load before executing javascript, resulting in running javascript in incomplete document.

This patch is to allow reland of v8::context patch in blink: https://codereview.chromium.org/263583002/
It seems that the valid document were luckily there when we run these tests before the blink CL, but the blink CL changes the timeline so it fails on these tests.

Fix channel check for fatal error suppression.

Fatal extensions errors should be suppressed on
stable and beta channels of Chrome. This fixes a
regression where they were instead suppressed on
other channels.
