fix: channel callback never cleaned up from window

[Legend-Master]

Fix #13133

Also:

• added a feature that allows passing the callback as the parameter of constructor of Channel so you can use it like this new Channel((message) => console.log(message))
• only go through the fetch process if the data is large enough for it to be faster

This change will require syncing the version of rust crate tauri and js package @tauri-apps/api, since this is marked as a minor I think we can do this right?

[FabianLars]

hmm, yeah. we've communicated that minor versions are synced a few times (even if we don't fully follow it) so it should be fine. not the first time in 2.x either 🤷

[FabianLars]

finally someone who agrees with me on that approach 😂

[Legend-Master]

This should significantly reduce the load in places like sending updater's download progress

[lucasfernog]

sample benchmark script:

pub fn spam(channel: Channel<tauri::ipc::InvokeResponseBody>) -> tauri::Result<()> {
  for i in 1..=255 {
    channel.send(tauri::ipc::InvokeResponseBody::Raw(
      std::iter::repeat(i).take(1024).collect(),
    ))?;
  }
  Ok(())
}

(change 1024 to whatever you want to test)

channel = new __TAURI__.core.Channel();
i = 0;
channel.onmessage = (m) => {console.log(m); i++; if (i === 255) { console.timeEnd('spam') } };
console.time('spam');
__TAURI__.core.invoke('spam', { channel });

@Legend-Master This is a BREAKING CHANGE.

I need to use channels to send binary data:

• https://github.com/pytauri/pytauri/blob/c738a5949859455e89e8095df1d0726831c29f1a/crates/tauri-plugin-pytauri/guest-js/src/index.ts#L94-L97
• https://github.com/pytauri/pytauri/blob/c738a5949859455e89e8095df1d0726831c29f1a/crates/pytauri-core/src/ext_mod_impl/ipc.rs#L301

Previously, the received data was an ArrayBuffer, but now it has become an Array.

[Legend-Master]

That's pretty much the only part not written by me in this PR (ebb919b) 😅, anyways, I'll take a look tomorrow

[WSH032]

Oh, my bad, I didn't notice that 😂
