feature: linux tray support

[jinzhongjia]

Now, the more general interface should be StatusNotifierItem, but gnome default not use this, gnome shell supports this via plugin

the specification: https://www.freedesktop.org/wiki/Specifications/StatusNotifierItem/

I will try to add this support

After waiting for the PR to be completed, maybe try to add macos support, although I don't have a mac device
