Remove several usages of `.gl-xs-w-full` utility

What does this MR do and why?

Remove several usages of .gl-xs-w-full utility

This removes some usages of the desktop-first .gl-xs-w-full utility. We are replacing them with mobile-first utils combinations. Some necessary utils were not yet part of GitLab UI, those have been added to a temporary stylesheet that will be migrated to GitLab UI in a follow-up.

Screenshots or screen recordings

Note: Only some screenshots and repro steps are provided. In some cases, I wasn't sure how to actually access the affected views. Considering that the fix is essentially the same in all cases, I did not put much effort into smoke-testing every single area so that I can move quickly towards getting rid of the (to-be) deprecated CSS util.
