feat(tvix/nar-bridge): support uploading NAR files r/8377

This ingests NAR files into the {Blob,Directory}Service, which are
already part of the AppState.

As we then need to correlate the root node to the uploaded PathInfo, we
need to keep a (short-lived) lookup table from NARHash to root node
around. We insert it into a `LruCache` after the NAR is uploaded, and
use `peek()` to do the lookup, which doesn't update the LRU list.
