Removed some unused at extends from SCSS
What does this MR do?
Delete some more @extend
s for #323021 (closed)
If the extend was close to the selector it was extending, I just combined the rules. This gives the same result but is cheaper for compiler. For simple ones I swapped CSS rules for util classes.
There are some minor CSS output changes, but no (intended) visual changes
Screenshots (strongly suggested)
