http-client-java, refactor crossLanguageDefinitionId (#5429)

code-model, move it to `Language`

Visible effect is that sync/async client should now have a
crossLanguageDefinitionId.
e.g.
```
    "todo.TodoItemsClient": "Todo.TodoItems",
```

Previous, it is null, e.g.

https://github.com/allenjzhang/typespec-e2e-demo/blob/main/todoApp/clients/java/src/main/resources/META-INF/todo_apiview_properties.json#L25

PS: should it be `null` instead of `"null"`?
