[net_interfaces] Extract ip_endpoint.mojom from host_resolver_service.mojom

Media Router needs ip_endpoint mojo struct to send data to MRP. ip_endpoint mojo struct is
currently defined in host_resolver_service.mojom. Seperate it out so that media_router.mojom
can include it.

[net_interfaces] rename address to address_bytes in ip_address.mojom

ip_endpoint.mojom has field "IPAddress address". When referencing underlying IPAddress in .js file,
we use: ip_endpoint.address.address.join('.'); The naming is a little confusing. Change address to
address_bytes in ip_address.mojom instead.

[Media Router] Make CastSinkExtraData take net::IPEndPoint instead of net::IPAddress

When implementing CastMediaSinkService and dual discovery, we decide to pass
MediaSinkInternal objects around in thread hopping methods. It will simplify
code if CastSinkExtraData takes one IPEndPoint field instead of both
IPAddress and port fields.

It seems unnecessary to update media_router.mojom since MRP does not need
port field. We need to introduce ip_endpoint.mojom and update extension code
if we would like to add port field to mojo.
