port to meson cargo

Use the new unstable meson cargo support. This simplifies the
meson.build script and allows to use crates such as clap that require
picking up features from Cargo.toml.

This also allows us to not embed thiserror in subprojects, and instead
use a wrap file with a custom meson.build and some patches to make it
compile without running its build.rs script.

-#+title: Gentoo Utils
-
-* Getting Started
-
-Gentoo Utils must be compiled from source currently. See the compiling from source section for more information.
-
-* Development :development:contributing:
-
-There are two main avenues for development:
-- compiling normally using packages via portage
-- using the podman container
-
-** Development without using a podman container
-*** Install Build Prerequisites
-- dev-lang/rust-bin-9999
-- llvm-core/clang
-- llvm-core/lld
-- sys-process/parallel (Needed for =check.sh=)
-- dev-build/meson
-
-Install build deps:
-#+begin_src bash :noeval
-emerge -a dev-lang/rust-bin-9999 \
-    llvm-core/clang \
-    llvm-core/lld \
-    sys-process/parallel
-#+end_src
-
-Compiling this project currently requires using a patched meson. Install patched meson:
-#+begin_src bash :noeval
-EGIT_OVERRIDE_REPO_MESONBUILD_MESON=https://jturnerusa.dev/cgit/meson emerge -a =dev-build/meson-9999::gentoo
-#+end_src
-
-** Development using a podman container
-The podman image comes with all the tools required to compile gentoo-utils.
-
-Clone the repo
-#+begin_src bash :noeval
-git clone https://git.epenguin.net/gentoo-utils/gentoo-utils.git
-cd gentoo-utils
-#+end_src
-
-Run the check script:
-#+begin_src bash :noeval
-podman run --rm --userns=keep-id -v $PWD:/workspace git.epenguin.net/gentoo-utils/gentoo-utils:latest ./check.sh
-#+end_src
