networkservices: add list resources for 10 deferred resources

[BBBmau]

Adds list-resource generation for 10 networkservices resources that were
scoped out of #18630 (P-17). These do not need #18304 (default_value on
optional location): either base_url hardcodes /locations/global/, or
location is required so the generated test captures it from state.

• google_network_services_agent_gateway
• google_network_services_edge_cache_keyset
• google_network_services_edge_cache_origin
• google_network_services_edge_cache_service
• google_network_services_endpoint_policy
• google_network_services_http_route
• google_network_services_lb_route_extension
• google_network_services_lb_traffic_extension
• google_network_services_service_lb_policies (beta)
• google_network_services_tcp_route

Still deferred pending #18304 (optional location default global):
Gateway, GrpcRoute, Mesh, TlsRoute.
