Improve "Included Branches" in Git Show

Hi Orgad, I have an other QtCreator/Git suggestion. Feel free to re-assign/ignore it, but I know you are familar with the correspondig code

Sometimes you need to figure out, in which remote branches/tags a specific commit exists/appeared first.

See the attached image for example, from this I can tell the commit is in 5.3.2 and 5.4, but not if its in 5.3.0

• I think the display could be splitted in local and remote branches (because the remote branch often is important if the patch was moved to an other branch)
• Sorting the list beginning with the oldest item first may be useful
• Maybe leave out branches in the middle, e.g.:

remote/5.3 remote/5.4 [...] remote/5.7 remote/5.8

PS: The commit in doubt is qtbase/b2d5e7805abe569a926eb087a75bd903261b734f needed for https://codereview.qt-project.org/#/c/171906/2
