Add `TcpStream::set_quickack`

[Darksonn]

The standard library has added methods for quickack in rust-lang/rust#129121. To mirror the standard library, we should add them to Tokio as well.

We don't need to mirror the extension trait part. It is fine to add the method directly on TcpStream.

Do we also need to bump the MSRV to 1.89.0?

[Darksonn]

No, I would not call the stdlib implementation. If there is one in socket2, then we can use that.

I'd like to take this task if no one is already working on it.
