cc: Update SpreadForStdDeviation to 3*sigma, and update tests.

A recent change (https://codereview.chromium.org/1980613003) updated one path
to use 3*sigma as the estimated spread for gaussian blurs in filters. This
propagates that change to the "filter outset" path, for consistency, and
updates test results accordingly (including one visually-indistinguishable
pixel diff).

It seems that we should probably keep the definition of Gaussian blur spread
consistent across cc::FilterOperations, so this is a minor change to do that.

(Discovered while making a change nearby.)

LGTM

We should really wean the code off of the GetOutsets() path.

One step toward doing that is how I found this. :)
