* meson: add support for testsuite

* meson: fix deprecation warning for run_command with unchecked return code

This would implicitly default to false, so if something bizarre happened
and the command errored out, meson would consider that fine. Now meson
emits a warning about this deprecated legacy behavior, suggests that it
will eventually change, and, most importantly, prevents a warning-free
build.

Suppress the warning by manually specifying the sensible behavior, which
is to fail on errors.

* meson: download catch2 on demand if a system version is unavailable

Produced by running `meson wrap install catch2` and checking the results
into git.

No modifications to the build files are expected; this makes use of
https://mesonbuild.com/Wrap-dependency-system-manual.html#provide-section

* style: pre-commit.ci fixes

* ci: add meson build to the CI

* ci: meson doesn't depend on ninja or or have a ninja extra

* ci: minor cleanup to Meson job
