Skip the noop Soong dep edge for api_domain and contributions

This allows us to skip the current visibility checks of certain
systemapi libraries like libsigchain. Instead of adding
`//build/orchestrator/apis` to the visibility of these libraries and
removing it later when the api_domains are collocated with their
contributions, drop the dependency edge creation for now

The dep edge will continue to exist in the generated Bazel workspace

Test: m nothing
