[mutter] context: Add :unsafe-mode property

[Marge Bot <marge-bot src gnome org>]

commit c62e86cb23d84dc1344cc72568b357272cd21647
Author: Florian Müllner <fmuellner gnome org>

    context: Add :unsafe-mode property
    
    We are going to restrict several sensitive D-Bus APIs to a set
    of allowed callers (like Settings or portal implementations).
    
    Add an :unsafe-mode property to the context to allow turning off
    those restrictions temporarily, in order to not get in the way
    of development/debugging.
