upgrade: report size of backing files, not internal storage size

upgrade.py is the only consumer of filelog.index, which I'd like
to eliminate from the file storage interface.

This commit changes the upgrade code to report the storage size
of files by looking at the size of the files backing its storage
instead of looking at the index.

I'm not convinced the approach in this patch will live very long
because it is relying on low-level attributes like "opener" and
"files," which may behave very differently on non-revlog storage.
But the data is only used for reporting purposes and it does get
us one step closer to eliminating "index."

A side-effect of this change is we now report the size of the revlog
index data - not just the revision data. I think this is more
accurate.

Test checkheadshook alias

  $ cat > ../main/.hg/hgrc <<EOF

  rollback completed

We can fix the head and push again

  $ hg up 6
  1 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ printf "first\nsecond" > b.txt
  $ hg ci -m "remove CRLF from b.txt"
  $ hg push -f ../main

  $ hg -R ../main rollback
  repository tip rolled back to revision 5 (undo push)

Test it still fails with checkallhook

  $ cat > ../main/.hg/hgrc <<EOF
