Flatten Meson build files

We use a new enough version that we can take advantage of a few shortcuts so that entire files don't need to be wrapped in a huge if.

Also, passing the dependency object directly to summary prints `YES`+the version, instead of just `YES`. Unfortunately, there's a bug with using a disabler, so some of them can't do that ([yet](https://github.com/mesonbuild/meson/pull/10949)).

Testing Done:
Configured with defaults and configured with
```
$ meson setup \
  -Davahi=disabled \
  -Dconsoleui=false \
  -Dgtkui=false \
  -Dintrospection=false \
  -Dkwallet=disabled \
  -Dlibgadu=disabled \
  -Dlibsecret=disabled \
  -Dmeanwhile=disabled \
  -Dsilc=disabled \
  -Dx=false \
  -Dzephyr=disabled \
  -Dunity-integration=disabled \
  -Dgplugin:lua=false \
  -Dgplugin:python3=false \
  -Dgplugin:vapi=false \
  -Ddynamic-prpls=bonjour
```
to disable almost everything.
