commit-graph verify: add progress output

For the reasons explained in the "commit-graph write: add progress output" commit leading up to this one, emit progress on "commit-graph verify". Since e0fd51e1d7 ("fsck: verify commit-graph", 2018-06-27) "git fsck" has called this command if core.commitGraph=true, but there's been no progress output to indicate that anything was different. Now there is (on my tiny dotfiles.git repository): $ git -c core.commitGraph=true -C ~/ fsck Checking object directories: 100% (256/256), done. Checking objects: 100% (2821/2821), done. dangling blob 5b8bbdb9b788ed90459f505b0934619c17cc605b Verifying commits in commit graph: 100% (867/867), done. And on a larger repository, such as the 2015-04-03-1M-git.git test repository: $ time git -c core.commitGraph=true -C ~/g/2015-04-03-1M-git/ commit-graph verify Verifying commits in commit graph: 100% (1000447/1000447), done. real 0m7.813s [...] Since the "commit-graph verify" subcommand is never called from "git gc", we don't have to worry about passing some some "report_progress" progress variable around for this codepath.
