[clipboard-manager] support hinting clipboard managers to exclude copied items from history

### Describe the problem

I am working on a project that requires copying secrets to the clipboard without having them saved on clipboard managers' history in order not to leak or expose secrets as plain-text. The behavior is very similar to how password managers copy secrets into clipboard.

### Describe the solution you'd like

In order not to break compatibility, I was thinking of adding either a single `write_secret` function for texts without supporting html and image, or three functions named `write_*_secret` for text, html, and image.

I did search through the `arboard` code base and there are platform specific extensions under `SetExtLinux`, `SetExtApple`, and `SetExtWindows` for each desktop platforms. Related functions that are implemented for each platform are as follows:

- **Linux** has `exclude_from_history`
- **Apple** has `exclude_from_history`
- **Windows** has `exclude_from_history`, `exclude_from_cloud`, and `exclude_from_monitoring`

According to [this](https://github.com/1Password/arboard/pull/155#issuecomment-3014681875) comment Linux support seems to be released in `3.6.0` version and this would require the plugin to bump `arboard` version to at least `3.6.0`.

There is also an issue to [promote `exclude_from_history` from extensions](https://github.com/1Password/arboard/issues/195), but they seem to be holding it due to the lack of `wasm` support.

I have an implementation [here](https://github.com/tauri-apps/plugins-workspace/compare/v2...umtdg:plugins-workspace:feat-clipboard-exclude?expand=1) using the functions mentioned above. I tested the implementation with both the example app and my application using a local path and seems to be working fine for now. I only tested the example app on Wayland and Apple Silicon, and i will try to test on Windows and X11 too. I am happy to submit a PR if this gets any traciton and until then I will be using my own fork.

### Alternatives considered

I could theoretically use the inner `arboard::Clipboard` in my app and bypass the plugin's abstraction layer, but I couldn't find a way to access to the `clipboard` field in the plugin's public API.

### Additional context

My use case is limited to desktop and I didn't do any research on if this can be added to mobile.
