This change includes only the basic nix handshake protocol handling and
sets up a client session. The only supported operation at this point is
SetOptions.
Additional operations will be implemented in subsequent cls.

Deduping early saves a fair bit of memory, but the extra hashing is
costly.
We switch to FxHash, since we don't need a DoS-proof hash, but we do
need it to be *fast*.

This vastly reduces the memory requirements, so we can run in ~40G RAM.

We switch to working with the underlying Arc<Bytes<u8>> type, since
Buffer<u8> is already essentially an OwningRef-esque subslice.
Because we're now working with an exposed Arc directly, we don't need
to have our own `unsafe impl StableAddress` any more.

We only care about ordering on the same variable, and we rely on the
release barrier provided by rayon's thread joining.
The comparison failing is always an error path, and we're indifferent
about which thread it fails on.

This was introduced in cl/9925 without any commit message, but this is clearly
not relevant to Tvix itself (it even says so in a comment in Cargo.toml).

packed_simd is deprecated, but we don't need very much SIMD:
* _mm256_set1_epi8 / vpbroadcastb (splat)
* _mm256_cmpgt_epi8 / vpcmpgtb (comparison)
* _mm256_movemask_epi8 / vpmovmskb (compress to bitmask)
This also simplifies the code by only vectorising the bare minimum,
since we just get a bitmask and operate in scalar mode as soon as
possible.
We don't need nightly Rust anymore: we're using only stable intrinsics.
