PackDirectory: Use PackFile to ensure we find preserved packs

Update scanPacksImpl and listPackDirectory (renamed to
getPackFilesByExtById) to use the new PackFile functionality to
validate file names and complete pack file sets (.pack, .idx, etc).

Most importantly, this allows a later change to rely on scanPacks() to
complete a packList that contains packs with the 'old-' prefix in their
extension.

This also eliminates duplication of logic for how to identify and
construct pack files.
