This adds (behind a new, default disabled feature flag) a new net error
code (ERR_CERT_SELF_SIGNED_LOCAL_NETWORK), which is returned for
certificate errors when the certificate is self-signed, and is being
used on a local network URL (either an RFC 1918 IP, or a URL that ends
in .local).
This is step one towards implementing go/betterselfsigned, for now this
only results in the regular SSL interstitial being triggered.
