This allows us to replace some very hacky and not correct string
concatentation in `HttpBinaryCacheStore`. It will especially be useful
with #13752, when today's hacks started to cause problems in practice,
not just theory.
Also make `fixGitURL` returned a `ParsedURL`.

This update contains d1266642a8722f2a05e311fa151c1413d2b9653c, which
is necessary for the TOML timestamps to get tested via nixpkgsLibTests job.
I need this for some `ParseURL` improvements, but I figure this is
better to send as its own PR.
I changed the tests willy-nilly to sometimes use
`std::list<std::string_view>` instead of `Strings` (which is
`std::list<std::string>`).

It is suppposed to be "post build" not "during the build" after all. Its
location now matches that for the hook case (see elsewhere in
`DerivationdBuildingGoal`).
It was in a try-catch before, and now it isn't, but I believe that it is
impossible for it to throw `BuildError`, which is sufficient for this
code motion to be correct.

It would have been nice to use std::views::enumerate here, but
it uses a signed difference type for the value_type:
> value_type = std::tuple<difference_type, ranges::range_value_t<Base>>
zip + iota has the same semantics as the code used to have, so there's
no behavior change here.
This is a nicer separation of concerns --- `DerivationBuilder` just
mounts the extra paths you tell it too, and the outside world is
responsible for making sure those extra paths make sense.
Since the closure only depends on global settings, and not
per-derivation information, we also have the option of moving this up
further and caching it across all local builds. (I only just realized
this after having done this refactor. I am not doing that change at this
time, however.)
Now, `DerivationBuilder` only concerns itself with `finalEnv` and
`extraFiles`, in straightforward unconditional code. All the fancy
desugaring logic is consolidated in `DerivationBuildingGoal`.
We should better share the pulled-out logic with `nix-shell`/`nix
develop`, which would fill in some missing features, arguably fixing
bugs.
I think this is a better separation of concerns. `DerivationBuilder`
doesn't need to to the final, query-heavy details about how these things
are constructed. It just operates on the level of "simple, stupid" files
and environment variables.
