A setting like `git.branchLogCmd` but for the commits panel

[OliverJAsh]

Is your feature request related to a problem? Please describe. I would like to be able to customise the log command used to generate the log in the commits panel so that I can do things like:

• show branch names
• use --first-parent to hide commits from branches I've merged into my branch
• show a tree of merge commits

Describe the solution you'd like Somthing like the git.branchLogCmd setting but specifically for the (small) commits panel.

Describe alternatives you've considered
