feat(tvix/store): From<&nix_compat::...::NarInfo<'_>> for PathInfo

Browse source 
This allows converting from the NarInfo falling out of the NarInfo
parser (which is a bit annoying to handle due to lifetimes) to the
PathInfo proto struct.

The narinfo field, containing most of the data from the original
NARInfo file, as well as the references (bytes) are populated.
The node field is not populated, because it requires ingesting the NAR
itself to describe the root node.
