[ssci] Added Shipped field to READMEs

This CL adds the Shipped field (and may update the
License File field) in Chromium READMEs. Changes were
automatically created, so if you disagree with any of
them (e.g. a package is used only for testing purposes
and is not shipped), comment the suggested change and
why.

See the LSC doc at go/lsc-chrome-metadata.
