[feat] Listening events for tray icons

[DWHengr]

Describe the problem

Listening events for tray icons, such as mouse entry/leave, etc. And return to the position of the mouse and the position of the system tray.

Describe the solution you'd like

pub enum SystemTrayEvent {
    Entry {
        tray_id: String,
        position: PhysicalPosition<f64>,
        size: PhysicalSize<f64>,
    },
    Leave {
        tray_id: String,
        position: PhysicalPosition<f64>,
        size: PhysicalSize<f64>,
    }
}

Is there any way to achieve similar functionality in the v1 version?

Similar to the "mouse-leave" and "mouse-enter" events in electronjs.
