Show branches and tags that contain a commit (#25180)

Now, you can see for a commit which existing branches and tags contain it.
You first have to click on the `load branches and tags` button, they are not preloaded by default.
All branches and tags are ordered descending by creation date.
You can even see without much hassle if the given commit is already part of the default branch.

Closes #25152
