This is the long awaited refactor of the NixSettings.
It allows one to set, unset and update any and all settings with a neat
and easy-to-use interface

See: cl/4840
When importing Python modules, we include `functional2` in the module
path, like this:
from functional2.testlib.fixtures.env import ManagedEnv
This means that python expects to see a file like
`functional2/testlib/fixtures/env.py`. We run `pytest` from `tests/` in
the `justfile` and have `tests/functional2/__init__.py` so `pytest` in
`meson` is able to find these imports.
However, language servers generally consider the `pyproject.toml` to be
the project root, so (e.g.) `pyright` is unable to follow any of the
`functional2` imports, leading to lots of spurious errors.
In cl/4840 I moved `tests/functional2/pyproject.toml` to
`tests/pyproject.toml`, which worked but was considered aesthetically
unappealing.
This diff is much larger but it's a more elegant solution.

So far, the environment used by `command` was completely leaky and the
one used by `nix` was very leaky despite it trying to be a "hermetic"
environment.
This commit moves the hermaticity to `command` and changes its
implementation to be not leak anything.
To achieve this, the following changes were also nessecary:
- the `files` and `snapshot` fixture now use the folder `test-home`
within the tmp_path directory by default, as the `HOME` environment
variable is set to there. (extraction not possible due to dependencies
of command etc also using this directory)

Documenting fetchTree is an exercise in frustration because of the sheer
amount of stringly typed everything in it. I do not know which fields
exist without reading the entirety of libfetchers. However, we can write
something slightly perfunctory but at least perhaps somewhat helpful
documentation-wise.
