meson: enable auto_features by default

[jtojnar]

We disabled them by default when they were introduced in

#42994

but enabling them probably makes more sense:

#54398
#63491

We will probably need to adjust dependencies like in #63491 all over the place.

Oops, wrong syntax.

The failures are fewer than I expected. Perhaps more will show up once we fix the libs.

• gnome-desktop: https://hydra.nixos.org/build/95237863/nixlog/1
• tracker-miners: https://hydra.nixos.org/build/95223638/nixlog/1 (probably fixed by gnome3.tracker-miners: enable auto_features #63491)
• girara: https://hydra.nixos.org/build/95199057/nixlog/1
• grim: https://hydra.nixos.org/build/95187039/nixlog/1

Pushed the fixes, time for round two. Did not rebase yet so that we could have clearer picture which failures are caused by this and which by something else.

Also, I will be leaving for a month of mostly-offline vacation without a PC soon, so feel free to finish this in my absence.

Sounds good 👍 I can finish this.
