[gnome-software/wip/nielsdg/gs-appuse-pspec: 33/34] gs-app: Use g_object_install_properties()

[Niels De Graef <nielsdg src gnome org>]

commit 01ec3c8065abbd6325abfcc6f46a6b8735fe3295
Author: Niels De Graef <nielsdegraef gmail com>

    gs-app: Use g_object_install_properties()
    
    By saving the `GParamSpec`s that are tied to the object and using
    `g_object_install_properties()`, we can prevent some unnecessary
    lookups to find the param spec from the property name.
