[RFC PATCH proxmox-backup 1/6] refactor: rename `ReuseStats` struct to `PxarArchiverProgressStats`

[Shan Shaji <s.shaji@proxmox.com>]

Earlier, the `ReuseStats` struct was used to count and show summary for
metadata mode. Since, the same counter will be used to show stats for
both legacy and data mode, rename `ReuseStats` struct to
`PxarArchiverProgressStats` and its corresponding propery inside the
archiver to `progress_stats`.
