Describe the bug

Systray apps on macOS can only be terminated by clicking on the systray Quit button.

This even interupts restart and shutdown of the OS (see screenshot).

How to reproduce

Try to quit the attached program by either clicking Quit in the dock or using the "Restart..." or "Shut Down..." function of macOS.
Neither will work.

package main

import (

	"fyne.io/fyne/v2/widget"
)

func main() {
	a := app.New()
	w := a.NewWindow("SysTray")
	w.SetContent(widget.NewLabel("Fyne System Tray"))
	w.Hide()

	if desk, ok := a.(desktop.App); ok {
		m := fyne.NewMenu("MyApp",
			fyne.NewMenuItem("Show", func() {
				w.Show()
			}))
		desk.SetSystemTrayMenu(m)
	}

	w.SetCloseIntercept(func() {
		w.Hide()
	})
	a.Run()
}

I have finally tracked this down...

GLFW terminates an app by closing all the windows.
And we have told an app with systray to not close when the windows are shut.

Not yet sure how to resolve this, probably some more complex fix to GLFW required...
