[FFe] Use tecla to display keyboard layouts

[Jeremy Bícha]

Explanation of FeatureFreeze exception
=======================================
GNOME 45 includes a new keyboard layout viewer named Tecla to replace gkbd-keyboard-display (old and written in GTK3). The Main Inclusion Request for this was approved in LP: #2026774 but I reverted the switch in the gnome-control-center, gnome-initial-setup, and gnome-shell packaging because the first release of Tecla crashed with some keyboard layouts. That issue has been fixed for the gnome-control-center & gnome-initial-setup integration.

Specific changes
================
1. Drop the Tecla patch from gnome-control-center and gnome-initial-setup
2. Have gnome-control-center and gnome-initial-setup depend on Tecla
3. Promote Tecla to main. The approved MIR is https://launchpad.net/bugs/2026774

(Both 1 and 2 have been done in Debian Unstable now.)

Later changes
=============
In my testing with GNOME Shell 45 Beta, there are still some issues with the Tecla integration. I'll file those issues upstream and we'd like to be able to switch GNOME Shell to use Tecla later this cycle. We would…

4. Drop the Tecla patch from gnome-shell
5. Have gnome-shell depend on Tecla
6. Demote libgnomekbd to Universe

Testing Done
============
I successfully completed Test Case 1 and the first 5 steps of Test Case 2 from

It's a low risk change since the component is only handling the display of the keyboard layout in a gtk dialog which is a pretty isolated feature and non essential to the use of the system

[Steve Langasek (vorlon)]

That looks straightforward, with an obvious rollback path. The gnome-shell switch should be evaluated based on where we are in the release cycle once its ready, and how smoothly the g-c-c change goes. FFe granted for the first part, g-c-c + g-i-s.
