[gnome-shell] main: Define global properties with 'var' instead of 'let'

[Florian Müllner <fmuellner src gnome org>]

commit 9e32ba61fd588353d473858a27bdf0cb0c508019
Author: Florian Müllner <fmuellner gnome org>

    main: Define global properties with 'var' instead of 'let'
    
    Symbols that are defined with 'let' are no longer visible outside
    the module that defines them. To unbreak the code base, define all
    non-private properties as global.
