These are required to support certain nix's local-overlay store
operations, it's safer to return empty results for these
operations than failing with "operation not implemented" errors.

This change contains 2 improvements to the tvix-store copy command:
1. Allows reading the reference graph from stdin, using `-` argument
2. Supports json representation produced by `nix path-info --json`
command.
In general it makes is easier and faster to import arbitrary closures
from an existing nix store with e.g the following command:
```
nix path-info ./result --json --closure-size --recursive | \
jq -s '{closure: add}' | \
tvix-store copy -
```

When uploading a Store Path to a Nix HTTP Binary Cache, Nix first does a
HEAD request for $outhash.narinfo, and if that's not found, for
`{narhash}.nar[.compression_suffix]`.
If the NAR is already present, only the NARInfo is uploaded.
Even though we don't have a service allowing to globally look up from
NARHash to root node, `root_nodes` in `AppState` at least contains
recently uploaded NARHashes.
If we find it in there, we can prevent Nix unnecessarily uploading NARs
if the same contents have already been recently uploaded.
We also promote this key, chances are high Nix will subsequently upload
a NARInfo referring to this NARHash.

Related functionality in vm.rs is also removed: vm.rs does not know

propagated as ErrorKind, were-as previously there was a split between
CatchableErrorKind and ErrorKind, where eventually CatchableErrorKind
would be converted to ErrorKind::Catchable.
