[sql] Ship Favicons recovery code to beta and stable.

[sql] Ship Favicons recovery code to beta and stable.

The code has been running without event on dev and canary for many
weeks, the histograms have changed in a manner consistent with
databases no longer being corrupt.  Everyone should share this.

Add some histograms to track the amount of data recovered.

jar@ for histograms
sky@ for code change.
pkotwicz@ just FYI.

The branch is coming, so I was thinking "Maybe I should land a finch experiment
beforehand!"  But when I thought on it, I couldn't think of any reason at all to
stage the rollout further.

Looking at later and prior runs for other CLs, AFAICT it's flake, so trying
again.
