Add APIs for finding default input sources

Subject: [PATCH 2/4] gnome-languages: Add function to detect non-latin layouts
If user chooses "Russian" we need to add "us" as well so they have
a way to input latin characters.
This commit adds a function to detect layouts that need supplemental
layouts to tag along.
