Add to //services/network Blink typemap variants needed by p2p

This is a preliminary step to Onion souping //content/renderer/p2p.

The following typemaps got added, and listed to [1]:

- services/network/public/cpp/ip_address_for_blink.typemap
  (based on ip_address.typemap)
- services/network/public/cpp/ip_endpoint_for_blink.typemap
  (based on ip_endpoint.typemap)
- services/network/public/cpp/network_interface_for_blink.typemap
  (based on network_interface.typemap)

Additionally, the following typemap files got listed in [1] as-is:

-  services/network/public/cpp/p2p.typemap
-  services/network/public/cpp/mutable_network_traffic_annotation_tag.typemap
