This controls whether tvix-castore has support for various cloud

Use this to control the set of feature flags for the object_store

In the future this can be used to enable/disable other cloud backends
too.
Without feature flags, `object_store` already supports the `InMemory`
and `LocalFilesystem` backends, and we also want to unconditionally
enable the `http` one. Make sure at least the construction of these
services is covered in the tests.
Similarly, the tvix-store crate, which provides the tvix-store CLI has a

It is pretty pointless to force the function argument if we are going to

that are not covered by Catchables (non-recoverable errors, infinite

This updates the parameters mkBootTest can be called with. It now
accepts a `path`, and then either importPathName needs to be set, or
isClosure needs to be set to true.
The former activates the existing functionality, tvix-store import is
used to import contents as a NAR-addressed store path.
The latter uploads the path as a closure (so including its references,
and keeping the store paths intact) to tvix-store.
We use nar-bridge, and the HTTP interface it provides to do this.
As `nix copy` can't be used inside a Nix build, we use
`pkgs.mkBinaryCache` to come up with the .narinfo and .nar files that
would be in a binary cache, and then use a bit of GNU Parallel and bash
to upload store paths ourselves.

Whenever this encounters an open_read(), it'll first check for more

ChunkedReader is constructed (which supports seeking backwards).
This currently is still a bit stupid, and doesn't compose, as
`ChunkedReader` uses `self` as the `BlobService` to ask for the
individual chunks.
In store composition future, we might want to compose this differently,
essentially constructing `ChunkedReader` with another `BlobService`
representing the entire hierarchy, so there's a chance to locally cache
things, and do less requests.

`build.rs` emits rerun-if-changed statements for all proto files, as
well as all include paths we pass it.
Unfortunately, due to protobufs include path rules, we need to specify
the path to the depot root itself as an include path, at least when
building impurely with `cargo`. This causes cargo to essentially always
rebuild, as it also puts its own temporary files in there.
Unfortunately, tonic-build does not chase down to individual .proto
files that are included.
Disable emitting these `rerun-if-changed` statements for now.
This could cause cargo to not rebuild protos every time, causing stale
data until the next local `cargo clean`, but considering the protos
change not that frequently, and it'll immediately surface if trying to
build via Nix (either locally or in CI), it's a good-enough compromise.

This brings some initial Nix wire format parsing code, used in the nix

one).
Thanks to embr, this code already exists, in
https://codeberg.org/gorgon/gorgon/src/branch/main/nix-daemon/src/wire.rs,
and we can vendor it into here, as EUPL is compatible with GPL (in that
direction).
The code uses the tokio::io Reader and Writer traits, not the ones from
the `futures` crate, as they provide some more convenient `read_u64_le`
functions.
More application-specific parsing code, as well as code to read strings,
or bytes are left out for now, as we want to be be more restrictive
w.r.t allowed max sizes, and need to parse bytes, not strings.
The code slightly diverges, as we have clippy looped into CI.
`Ok(…?)` can be turned into just the inner expression, and
some .and_then can be expressed in a simpler fashion.
