Title:
Some emoji in emoji chooser are black & white

Bug description:
Impact
======
Some emoji in the emoji chooser show as black & white.
This is because these emoji default to "text presentation" instead of
"emoji presentation".
More information and a screenshot can be found in the pango issue
linked below.
Test Case
=========
In an app like gedit, right click in the text area and select Insert Emoji
Browse through the emoji list. All should be in full color.
Regression Potential
====================
This fix was included in the gtk 3.24.2 release. There is a standing
microrelease exception for GNOME point releases.
GTK 3.24 was a big enough release (with some bumped dependencies) that
it's not very practical to push to Ubuntu 18.04 LTS so we selectively
cherry-pick fixes there.

Other Info
==========
This adds an extra variation selector byte to each emoji added via the emoji
chooser. (Many emoji are made up of multiple bytes.) This will not affect emoji
added to GTK apps in other ways, such as copying and pasting from an app where
the emoji doesn't have that variation selector added to it.
This bug is fixed in gtk 3.24.2. Its SRU for cosmic is being tracked
in LP: #1808233
