git_graph: Add remote support for search operations (#55167)

### Motivation 

This is the second of three PRs to add remote/collab support for the git
graph and is a follow-up to #54468. I'm adding remote support for the
search because it's not user accessible without the initial graph fetch
having remote support, so it allows us to merge this without having to
add full remote support. Collab guest support will be added in a
follow-up PR.

#### Summary

For large repos, searching can take a while to fully stream in all
matched results. For example, running a basic search on the Linux repo
took over 10s for me. Because of that, we want to stream search results
in chunks to downstream users to keep the time-to-first-match low. After
this change, the first chunk gets sent back after ~50ms on the Linux
repo from receiving the request.

In order to accomplish that, I added a new proto client API that allows
for a request to map to n responses. e.g.

```/dev/null/example.rs#L1-1
client.add_entity_stream_request_handler(Self::handle_search_commits);
```

Note: The proto API isn't supported over collab yet, that will be
another PR
