fix(vcs): show branch actions in the Git Log commit menu (#1852)

Right-clicking a commit with branch labels offered commit actions only. The menu now has a Branch 'name' submenu with the existing branch actions for each branch at that commit other than the current one, grouped under Branches when there are more than two, and keeps Rebase onto Selected Commit for commits without branches. The actions run against the commit's repository in a multi-repository project.
