ci: use meson setup build instead of meson build

The old "meson build" build command was actually deprecated a few months
ago*. It turns out that you're supposed to use "meson setup build"
instead which has been around for years. Go ahead and be a good citizen
and update this in the CI. Also replace any mention of "meson build"
with "meson setup build" in the documentation as well and change the one
random hardcoded string we have in meson.build to "meson configure
build" (might as well).

 of all the build options via `meson configure build`. You could also just simply
 look at the `meson_options.txt` file. Logs are stored in `meson-logs` within
 your build directory.

-    meson build

     meson compile -C build
