refactor(tvix/store/fs): Decouple TvixStoreFs from Nix concepts r/7222
To support tvix builds, we need to be able to use the `TvixStoreFs` to materialize the sandbox's /nix/store filesystem with just the list of inputs needed for the build. Currently we'd need to seed an in-memory `PathInfoService`, which includes more functionality than what is required for `TvixStoreFs`. Additionally, the `PathInfoService` is specific to Nix. By decoupling `TvixStoreFs` and `PathInfoService`, we allow for usage of `TvixStoreFs` with `tvix-castore` without needing a `PathInfoService`. This introduces a new `RootNodes` trait which provides a way for the filesystem to look up CA nodes via their basename in the root directory of the filesystem. We then implement `RootNodes` for any `PathInfoService`. Additionally, the filesystem root inode tracker now stores basenames rather than `StorePath`s since `StorePath`s are specific to Nix. As a followup we can rename `TvixStoreFs` to `TvixCaStoreFs` and move it to the `castore` crate (or its own crate). b/341 Change-Id: I928372955017c23b1bf2b37190cbc508a4ed10d5 Reviewed-on: https://cl.tvl.fyi/c/depot/+/10363 Tested-by: BuildkiteCI Reviewed-by: flokli <flokli@flokli.de>
