[gnome-shell/eos3.8: 68/255] Allow using the Alt-Tab switcher from the Overview

[Matthew Leeds <mwleeds src gnome org>]

commit 7c5d7bf3111f66b0c6c7589e9289251222a5fe61

    Allow using the Alt-Tab switcher from the Overview
    
    This enables using the switcher both from the windows picker and
    the desktop (i.g. icon grid), which are rendered in overview mode.
    
    Besides, this patch also makes sure that the overview gets hidden
    when selecting and application via the Alt-Tab switcher, so that
    it gets properly shown on top of the desktop in any case.
