A pool of Workers is now used to process Sass render requests. This change allows multiple synchronous render operations to occur at the same time. Sass synchronous render operations can be up to two times faster than the asynchronous variant. The benefit will be most pronounced in applications with large amounts of Sass stylesheets.

Initial benchmarking with test projects containing large amounts of Sass stylesheets resulted in an additional ~15% total build time improvement over #20740
