Revert "KStandardItemListWidget: handle RtL drawing properly"
This revert fixes the regressions
- https://bugs.kde.org/show_bug.cgi?id=451704,
- https://bugs.kde.org/show_bug.cgi?id=451341 and
- ddba4f5f (comment 423372).
We have to revert because the Release Candidate for 22.04 will be released in four days.
If nobody stops me, I will also revert for master since there has been no work on two of the three regressions mentioned above and I don't want to be the one on the lookout that they will actually be resolved until the next release (anyone volunteering?). I'd rather see a new MR which contains both the changes being reverted here and the fixes all in one go.
