[v4,10/10] commit-graph write: emit a percentage for all progress

Commit Message

Change the "Annotating commit graph" progress output to show a
completion percentage. I added this in 7b0f229222 ("commit-graph
write: add progress output", 2018-09-17) and evidently didn't notice
how easy it was to add a completion percentage.

Now for e.g. linux.git we'll emit:

    ~/g/git/git --exec-path=$HOME/g/git commit-graph write
    Finding commits for commit graph among packed objects: 100% (6365442/6365442), done.
    Annotating commit graph: 100% (2391666/2391666), done.
    Computing commit graph generation numbers: 100% (797222/797222), done.
    Writing out commit graph in 4 passes: 100% (3188888/3188888), done.
