[RayService] Remove serve v1 API

[architkulkarni]

This is the minimal PR to remove the Serve v1 API, which is removed in Ray 2.9.0.

• Deleted ServeDeploymentGraphSpec from the RayService CRD, along with its child data structures RayActorOptionSpec and ServeConfigSpec
• Ran make manifests
• Ran make sync

Followup work will include

• Remove the Serve v1 API from apiserver and proto.
• Delete utils.SINGLE_APP and utils.MULTI_APP and unify the codepaths that used them

Could you double check dashboard_httpclient.go and fake_serve_httpclient.go? I think some functions and variables can also be deleted.

Do we still need this test?

@kevin85421 Yeah, would you prefer to do it all in this PR or is it okay to do it in a followup PR? The current PR is the minimal PR that removes the v1 API.

I've done this in the following commit on a followup PR: f439814

We can merge this PR and then merge the followup PR, or if you prefer I can just add that commit to this PR.

Both are fine for me. I like this PR. This PR makes the codebase more elegant!
