Add gl-max-w-48 & gl-max-w-58 CSS utilities
requested to merge preetidevsang/gitlab-ui:504-use-sass-functions-for-box-shadow-utilities into main
What does this MR do?
added the two $gl-spacing-scale-… variables to the variables.scss file (probably between lines 22 & 23)
added the two .gl-max-w-… classes (as SCSS @mixins) to the sizing.scss utility mixins file
Closes #1693 (closed)
