Use PhutilConsoleProgressBar for the repository/reparse.php script

Summary: The output from this script is too verbose... all that I care about is the overall progress.

Test Plan:
Ran the script on a large repository.

./scripts/repository/reparse.php --all XYZ --message
NOTE: This script will queue tasks to reparse the data. Once the tasks have been queued, you need to run Taskmaster daemons to execute them.

QUEUEING TASKS (92,969 Commits):
[                                                                  ]   0.1%
