Wrongly defined `delta` on messages

Describe the bug

We define a delta on messages (https://github.com/microsoftgraph/msgraph-sdk-python/blob/9542fa0b95c58822968116896048a00fe911eda4/msgraph/generated/users/item/messages/messages_request_builder.py#L140) that can be used like await client.users.by_user_id(some_id).messages.delta.get(), however the API doesn't support this (yet) and thus simply returns Unsupported request: Change tracking is not supported against 'microsoft.graph.message'.

Tracking changes on messages, according to the docs, only exists on a per mailfolder basis. message resource type

Expected behavior

Not having it defined (or get Graph API to finally support tracking).

How to reproduce

Given some GraphServiceClient client, a user or mailbox with id some_id and appropriate permissions call:

await client.users.by_user_id(some_id).messages.delta.get()

Other information

Disclaimer this might as well not be a msgraph-sdk-python issue but generally wrongly defined in the msgraph-sdk. I'm reporting it here because I only checked here.

从第 140 行附近的 users/item/messages/messages_request_builder.py 定义开始，并将其与 Microsoft Graph message 资源文档进行比较。检查 messages delta request 的暴露方式，并确认不受支持的 API 行为；当 invalid messages-level delta operation 不再定义，或以其他方式与文档所述的 per-mailfolder 支持保持一致时，即表示完成。
