Revert Fast tab closure and dependent CL

Revert r205149 (Fast tab closure) and dependent CL r207181 (Move histograms and supporting code that don't belong in content out) since it breaks a bunch of systems.

Mechanical revert of problematic CLs, setting NOTRY so we can land this in the face of flaky bots.
