Original change's description:
> Refactor how additional certificates are configured.
>
> Previously they were set through CertVerifier::Config and passed into
> CertVerifyProc::Verify on every verification attempt. This also means
> they needed to be passed from the browser to the network service on
> configuration, and then passed back to the cert verifier service on
> every verification attempt.
>
> The new flow stores them in the CertVerifyProc instance and uses the
> CertVerifierWithUpdatableProc interface to update them.
>
> (this CL borrows some of the CertVerifierServiceUpdater parts from https://chromium-review.googlesource.com/c/chromium/src/+/4909292)
