Per-user default emoji font(s). Multiple fonts may be listed in
case a font does not support all emoji.
Note that fontconfig matches color emoji fonts preferentially,
so if you want to use a black and white font while having
a color font installed (eg. Noto Color Emoji installed alongside
Noto Emoji), fontconfig will still choose the color font even
when it is later in the list.
