[Plasmoid]Make device menu use PC ContextMenu
Summary
Change the three dotted menu to use PlasmaComponents ContextMenu. This prevents menu from staying open on other system tray's applets. Wayland still has that issue, happens in other menus too. And change menu icon into a hamburger menu.
Test Plan
Before:
Open the menu, and then open an other applet. Menu will stay open on the left. Even if change windows and open the system tray, will still be there.
After:
Use X11. By clicking, for example volume applet, menu will minimize. Will need to click again to open the applet.
