[gnome-shell] tests: Add a box-shadow test

[Florian Müllner <fmuellner src gnome org>]

commit 51bfbca2f1903a6a50c3af2e6801cb086c5b68bd

    tests: Add a box-shadow test
    
    The original support for CSS based shadows has been extended with
    support for an optional spread radius and the 'inset' keyword,
    so with the additional complexity a dedicated test case looks
    appropriate.
