Customize: Maximize height of Custom CSS textarea without causing doubled scrollbars.

Textarea will fill vertical height of Custom CSS section for browsers that support `calc()` and when plugins don't add other controls to the section. Also run CSS autoprefixer.

Props michaelarestad, westonruter.
See #35395.
Fixes #38755.
