Port the project from autotools to meson. All build options are
preserved with the same semantics.
The goal of this change is to produce the same set of files as the
current autotools approach: libraries with correct SONAME/version,
headers, pkg-config files, GObject introspection data, Python extension
modules, D-Bus interface and configuration files. This is done to enable
a one-liner test command running all available test suites.
The only thing we drop is the `make docs` target as it's rarely used and
docs can be generated easily with sphinx directly. They are also not
required for testing.
The Rust workspace is built via a custom target that invokes cargo and
uses SYSTEM_DEPS_* environment variables to point the libgpiod-sys and
gpiosim-sys crates at the locally built C libraries.

I think this is the third or fourth time we try this, maybe this time
it'll stick. This is a port of the current autotools build system to
meson & ninja. A PoC yocto recipe update[1] can be used for testing.

Builds/unit tests against the supported Python matrix pass after meson migration:
https://github.com/vfazio/libgpiod/actions/runs/24777629426
Python wheel generation shouldn't be impacted but tested generate_pypi_artifacts.sh
just in case and it continues to work AFAICT.

While running testing, I did get a notice for a "deprecated" feature:
NOTICE: Future-deprecated features used:
* 0.64.0: {'copy arg in configure_file'}
https://mesonbuild.com/Release-notes-for-0-64-0.html#fscopyfile-to-replace-configure_filecopy-true
https://mesonbuild.com/Reference-manual_functions.html#configure_file
Used here:
bindings/python/gpiod/meson.build: configure_file(input: f, output: f, copy: true)
bindings/python/tests/gpiosim/meson.build: configure_file(input: f, output: f, copy: true)
bindings/python/tests/system/meson.build: configure_file(input: f, output: f, copy: true)
bindings/python/tests/meson.build: configure_file(input: f, output: f, copy: true)
This may be intentional, but figured I'd mention it just in case.

docs/building.rst also needs an update with that :).

This effectively leaves catch2 optional even if cxx && tests is mandated
(if catch2-with-main fails to yield a result and catch_all.hpp does
not exist).
I think either this lookup should mandate it to exist if cxx && tests
are chosen OR the executable() in bindings/cxx/tests/meson.build has to
be made conditional on the catch2_test_dep?
As it stands, it does not compile on Fedora (which only ships an old
catch2 version that does not have catch_all.hpp).

Setting value: 'disabled' on all these options keeps them disabled even
when running with meson setup --auto-features=enabled (which is what
distros like Fedora do to ensure they catch new options).
So I am not sure if all of these should have presets? I think they could
just be left out and be automatically be negotiated by their dependencies
being discovered?
Otherwise people risk bumping libgpiod but forgetting to package up new
tools like the dbus daemon.
