Expected Behavior

(Using gnome as an example)

$XDG_DATA_DIRS/xdg-desktop-portal/gnome-portals.conf

[preferred]
default=gnome;gtk;
org.freedesktop.impl.portal.Secret=gnome-keyring;

$XDG_CONFIG_HOME/xdg-desktop-portal/gnome-portals.conf

[preferred]
org.freedesktop.impl.portal.FileChooser=gtk;

The user expects the following:
Calls to the FileChooser interface will be processed by x-d-p-gtk.
Calls to the Secret interface will be processed by x-d-p-gnome-keyring.
Calls to any other interface will be processed by either x-d-p-gnome or x-d-p-gtk (because of default=gnome;gtk;)

Current Behavior

Calls to the FileChooser interface will be processed by x-d-p-gtk.
Calls to any other interface will fallback to the deprecated backend choosing method (based on UseIn & Lexicographical ordering)

Anything else we should know?

Currently, x-d-p looks for $DIR/portals.conf if $DIR/$DESKTOP-portals.conf doesn't exist.
If $HIGH_PRECEDENCE_DIR/$DESKTOP-portals.conf exists, should $HIGH_PRECEDENCE_DIR/portals.conf be read before $LOW_PRECEDENCE_DIR/$DESKTOP-portals.conf or skipped?
