Subject: [PATCH] Upgrade theme to Breeze GTK on startup

Summary:
Also apply it, if the config is empty. This is a port of kconf_update
script from `breeze-gtk` repo, but this time it use gtkconfig kded
module methods to manipulate config (to avoid code duplication and to
write config to all possible configuration storages).

BUG: 416635
FIXED-IN: 5.18.0

Test Plan:
# Remove `gtk-theme-name=` line in `~/.gtkrc-2.0` file or change it to `BreezyGTK`, `Orion` or `oxygen-gtk`
# Run `gtk_theme` executable from `kconf_update` build directory. Line should appear/cahnge to `Breeze`
# Remove `gtk-theme-name=` line in `~/.config/gtk-3.0/settings.ini` file or change it to `BreezyGTK`, `Orion` or `oxygen-gtk`
# Run `gtk_theme` executable from `kconf_update` build directory. Line should appear/cahnge to `Breeze`, also it should be changed in dconf in `org.gnome.desktop.interface.gtk-theme` prefix and in `~/.config/xsettingsd/xsettingsd.conf` file (`Net/ThemeName "Breeze"` line)
