Region marker folding has been added to CSS/SCSS/LESS.

Now in CSS you could use /* #region */ and /* #endregion */ to denote a folding region.
In SCSS/LESS you can also use // #region and // #endregion.
You can also put contents after #region, for example /* #region header */.

This makes CSS/SCSS/LESS to have 3 types of folding in total:

• Region Marker Folding
• Brace Folding: { and }
• Multiline Comment Folding: /* */ comment that spans through multiple lines

Test that in the three languages, folding work as you expected. And in incomplete cases, such as region with open but not close marker, no folding marker would be shown.
