shell: Ignore non-toplevels for ShellWindowTracker::tracked-windows-changed

Browse Source 
Popups and other override-redirect windows are meaningless to everything
that depends on the ShellWindowTracker. Ignoring those windows will result
in less ShellApp::windows-changed signal emissions, and less activity in
the AppMenuButton and everything else that depends on them.

Reduces gnome-shell CPU activity while typing on the Epiphany addressbar,
as the pop up animation there results in a number of xdg_popup being
created and destroyed.
