Added emitter support to init template

[allenjzhang]

Init template now supports a list of emitters for user to choose from to be included in the project.

Artifacts affected:

• package.json Emitters with optional package version are added
• tspconfig.yaml emitters with options are added to emit and options section. Currently options do not support token replacement
• optional messages are display after scaffolding for any additional environment setup instructions

Here is a sample template. We will evaluate whether to make it a built-in template:

{
  "azure-core": {
    "title": "REST API with client or server project",
    "description": "Create a project representing a generic REST API with options to include client or server project",
    "compilerVersion": "0.63.0",
    "libraries": ["@typespec/http", "@typespec/rest", "@typespec/openapi3"],
    "config": {},
    "emitters": {
      "@typespec/openapi3": {
        "selected": true,
        "description": "Generate OpenAPI 3.0 or 3.1 specification",
        "options": {
          "emitter-output-dir": "{project-root}/openapi/"
        },
        "version": "0.49.0"
      },
      "@typespec/http-client-csharp": {
        "description": "Client: generate CSharp client",
        "options": {
          "emitter-output-dir": "{project-root}/client/csharp/generated"
        },
        "message": "Please ensure dotnet SDK has been installed. Download from https://dotnet.microsoft.com/download"
      },
      "@typespec/http-server-csharp": {
        "description": "Server: generate ASP.NET Core server",
        "options": {
          "emitter-output-dir": "{project-root}/servers/aspnet/generated"
        },
        "message": "Please ensure dotnet SDK has been installed. Download from https://dotnet.microsoft.com/download"
      }
    }
  }
}
