This commit enables the parametrization for "legacy-combined" protocol.
All failing tests with that have been either fixed or disabled. Notably:
- A couple of tests (e.g. involving builders) could be made to work with
a non-local store, but this would require some refactoring to testlib in
order to make certain configuration settings generic over local and
remote operations. We've disabled those for now, in order to make
progress
- The store tests all run locally only because of their nature
- The flakes tests also all run locally only because my energy for
fixing them is limited (and it's a *lot* of test failures, with probably
little overall benefit in terms of test coverage)

diverted stores are only necessary when the logical store paths of
objects matter for the test itself, such as for derivation hashes,
substitution from golden sample nars, or actual tests of the store
diversion functionality. all other tests can use undiverted stores
to run, especially since only linux can build in diverted a store.

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.

Currenlty one is required to always write the bulky `mark.parametrize`
with indirect and things
This commit adds a custom decorator for usage of files, which hides the
parametrization complexity from the user.

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)
Fixes: #847, #848

Snix's nar-bridge[1] stores NARs under a different URL, i.e.
`nar/snix-castore/<hash>.nar` rather than `nar/<filehash>.nar`. Right
now, when copying into such a store via the http binary-cache, we'd end
up with wrong cache entries that point to the wrong NAR URL.
On Hydra, this is a fatal error, i.e. builds that depend on previously
built paths (that were written to the cache before by the queue runner)
would be aborted because of that.
This patch removes the caching since we'd have to re-fetch the narinfo
to do taht and this can also happen the next time, the narinfo is
queried. Also, removes the negative cache entry indicating that the
store-path doesn't exist in the store.
We don't have any coverage for http-stores so far, so I wrote a small
testcase for the "default" case and the nar-bridge case in functional2
since it has a very nice fixture for an HTTP server ready. I'm aware
that there's a CL for a nicer cache server[2], but given I'm down a
pretty deep rabbit hole by playing around with Snix, I decided to not
finish the CL and write something small for the tests in here. This can
be replaced by the fixtures from that CL later on as well.
