fix(@angular/build): disable Worker wait loop for Sass compilations i…

…n web containers

The Sass Worker by default uses an Atomics-based wait loop to improve performance while waiting for messages. This
loop relies on the synchronous API `receiveMessageOnPort`. While this works well in Node.js, the web container
execution environment does not currently support passing transferable objects via `receiveMessageOnPort`.

Closes: #27723
