Revert "Enable VizHitTestDrawQuad feature by default on TOT for cros."

This reverts commit b5edc37e.

Reason for revert: suspected to cause flaky failures in
SitePerProcessBrowserTouchActionTest.EffectiveTouchActionPropagatesAcrossNestedFrames
While https://chromium-review.googlesource.com/1053907 enabled
the VizHitTestDrawQuad feature in fieldtrial_testing_config.json,
it doesn't seem to be applied to content_browsertests,
so this CL actually enabled that feature in this test and
possibly caused the flakiness. See crbug/910586.
