Require meson 1.0.0

We started using the verbose argument in tests, but that was added in 0.62.0.
But since 1.0.0 is everywhere, it just makes sense to require that for now as
we're not using/requiring anything from a newer meson version.

Testing Done:
Configured and made sure the warning was gone. Also ran with the turtles.
