Function solana_runtime::snapshot_utils::get_snapshot_accounts_hardlink_dir

fn get_snapshot_accounts_hardlink_dir(
    appendvec_path: &Path,
    bank_slot: Slot,
    account_paths: &mut HashSet<PathBuf>,
    hardlinks_dir: impl AsRef<Path>
) -> Result<PathBuf>

From an appendvec path, derive the snapshot hardlink path. If the corresponding snapshot hardlink directory does not exist, create it.
