[4.2] Reduce number of permission columns

[chmst]

Pull Request for Issue # .

Summary of Changes

The permissions overview contains 5 columns which contain always the same value because these are global permissions.
This PR extracts global permissions from the list of possible actions and displays the result in a single line.

It does not resolve the issue #23628. Horizontal scrolling appears in all screens where the table heading enforces horizontal scrolling, not only here. As soon as the table width cannot be reduced to fit the viewport, a horizontal scrollbar appears.
We resolve this in other tables by hiding some olumns, but on the permissions this is not possible.

Testing Instructions

Have a look on the permissions of a user before and after the patch.

I've restored the previous results from human tests in the issue tracker since the commit after that was just a code style change regarding white space.
