Update gtk4 emoji chooser for Unicode 16

[Jeremy Bícha]

Impact
------
Ubuntu has included Google's color emoji font by default for years. Annually, the Unicode Consortium releases a new Unicode standard with new emoji. Internet communication platforms quickly adopt the new emoji and it's important that those emoji also work on the latest Ubuntu release.

https://blog.emojipedia.org/whats-new-in-unicode-16-0/

This is a follow up to LP: #2083629 which updated the color emoji font to support the new emoji.

This updates the GTK4 emoji chooser that can be used in apps like gnome-text-editor

Test Case 1
---------
1. Be sure fonts-noto-color-emoji 2.042-1 is installed. On Ubuntu 24.04 LTS, this is as simple as running
sudo apt install --mark-auto fonts-noto-color-emoji=2.042-1

For Ubuntu 24.10, you can download the .deb from
https://launchpad.net/ubuntu/+source/fonts-noto-color-emoji/2.042-1/+latestbuild/amd64
and then run something like
sudo apt install --mark-auto ./fonts-noto-color-emoji_2.042-1_all.deb

2. After installing the font, restart your computer.

3. Install the updated gtk4 packages.

4. Run gnome-text-editor. Right click in the text area and choose Insert Emoji.

5. Search for fingerprint. No results should be shown.

Test Case 2
------
1. Be sure fonts-noto-color-emoji 2.047 is installed. On Ubuntu 24.10, this font version should already be installed.

By the time this GTK3 update reaches noble-proposed, fonts-noto-color-emoji 2.047 will likely be in noble-updates. If not, install it from noble-proposed instead.

2. Restart your computer.

3. Install the updated gtk4 packages.

4. Run gnome-text-editor. Right click in the text area and choose Insert Emoji.

5. Search for fingerprint. Click the blue fingerprint result. It should be inserted into your document.

What Could Go Wrong
-------------------
This is roughly a backport of the emoji chooser update from GTK 4.16.8. This was split from a full update to 4.16.8 for Oracular to simplify the SRU. Since the upstream GTK developers only supports one stable series of GTK4 at a time, this change was not included in any upstream 4.14.x release (for Ubuntu 24.04 LTS).

This SRU is limited to updating the data used to generate the GTK4 emoji chooser.

If the emoji chooser is broken, people can:
1. Use the GNOME Characters app (installed by default) to choose emoji instead and copy and paste them where needed.
2. Copy and paste emoji from the web, such as from https://emojipedia.org/

This doesn't affect gtk3 apps like gedit (which is not installed by default for Ubuntu 24.04 LTS and 24.10).

Other Info
----------
We are also updating the gtk3 emoji chooser in LP: #2096777

This change could be backported to Ubuntu 22.04 LTS but the Ubuntu Desktop team has limited capacity so we are encouraging people who care about improvements like this to upgrade to Ubuntu 24.04 LTS.

Debian customizes the build in debian/rules using a copy of the binary emojibase data in debian/missing-sources/ to build the emoji chooser data from source (gtk upstream ships the output of that command instead). (Yes, that still isn't ideal because the emojibase data is itself binary data that some day should be built from source in Debian too.)

Therefore to update the emoji chooser data, we only need to update the emojibase copy instead of updating to the new gtk3 release or cherry-picking upstream commits as patches.
