trace2:data: pack-objects: add trace2 regions
When studying the performance of 'git push' we would like to know how much time is spent at various parts of the command. One area that could cause performance trouble is 'git pack-objects'. Add trace2 regions around the three main actions taken in this command: 1. Enumerate objects. 2. Prepare pack. 3. Write pack-file.
