DNS over HTTPS not used when getting system DNS configuration or when system DNS configuration is not available

Project Member Reported by mmenke@chromium.org, Oct 8

Issue description

HostResolverImpl only uses DNS over HTTPS when dns_config.is_valid() is true, which is only the case when we can get a list of nameservers to use from the system.  However, we have a separate list of DNS over HTTPS nameservers that we can use without needing the system DNS configuration.

It seems like we should ideally try DoH before falling back to GetAddrInfo in those cases.
