Show commit-related info in all branches
<!-- This template is a great use for issues that are feature::additions or technical tasks for larger issues.-->
### Proposal
When we're comparing commits between branches, it's hard to know the commit-related info since GitLab only shows the number of commits in the main branch (i.e master) but none in other branches.
It would be helpful to also show the commit-related info in other branches, along with the last commit code and when this commit was done.
It would be even better if GitLab can show how many commits a branch is behind/ahead the main branch.
So, for example one changes to another branch, say branch "foobar", she can see:
"This branch is 20 commits ahead, 3 commits behind master"
Additionally, we can also know the following info:
"[userName] [commitMessage] [commitCode] [commitDate] [number of commits]"
i.e
"LinusTorvalds [BugFix] Add Mac compatibility driver 122f45f on Dec 12, 2021 200 commits"
<!-- Use this section to explain the feature and how it will work. It can be helpful to add technical details, design proposals, and links to related epics or issues. -->
<!-- Consider adding related issues and epics to this issue. You can also reference the Feature Proposal Template (https://gitlab.com/gitlab-org/gitlab/-/blob/master/.gitlab/issue_templates/Feature%20proposal%20-%20detailed.md) for additional details to consider adding to this issue. Additionally, as a data oriented organization, when your feature exits planning breakdown, consider adding the `What does success look like, and how can we measure that?` section.
