Make IsIPv6Reachable comply with network-bound URLRequestContexts

Currently, IsIPv6Reachable checks if the current default network is a
WiFi network. This is not correct for network-bound URLRequestContexts
where the default network network won't necessarily be used for DNS
lookups.

Allow instead to also create network-bound HostResolverManagers through
CreateNetworkBoundHostResolverManager. This is to allow each
network-bound URLRequestContext to use its own standalone
HostResolverManager (as agreed in crbug.com/1309094).

Note: network-bound HostResolverManagers don't need to listen to network
changes event for the same reason as other network-bound entities.

To keep things working this CL also updates network-bound lookups
unittests and URLRequestContextBuilder::BindToNetwork to make use of
CreateNetworkBoundHostResolverManager and
CreateStandaloneNetworkBoundResolver respectively.
