Platform-plugin support for QSystemTrayIcon.

Implement QPlatformSystemTrayIcon providing QPA-plugin-support for
system tray icons. Make QSystemTrayIcon use this as new backend.

Ported over qsystemtrayicon_mac.mm to qcocoasystemtrayicon.mm to provide
Cocoa support for the new interface. It had to be changed to match the
interface, especially for icon and menu handling.

This interface is made to not use QStyle or QMenu which are related
classes of QSystemTrayIcon. It's therefore not introducing QtWidget
dependency into the platform plugin.

Task-number: QTBUG-20978
