Convert TalkatuToolbar to GTK4

This is rather straightforward, because it simply involves replacing a toolbar with a box using a 'toolbar' style, and then running conversion on the `.ui` file.

Testing Done:
Compiled only the `talkatutoolbar.c.o` which passed. Also ran the `.ui` file through the GTK4 previewer.

# Building
Talkatu uses [meson](https://mesonbuild.com) as it's build system.
Meson requires you to build in a directory other than the source directory.
To compile you can use the following commands:
```
meson build
cd build
ninja install
```
