How to implement a backend extension execution of CPU-consuming operations without affecting the front-end UI interaction blocking problem？

When I use the backend extension to call the node module to compile my project code, during the compilation process, I found that I was operating the file tree at this time, and found that only loading did not respond quickly.

@zhaomenghuan I cannot be certain without looking at the source code of your changes, but you should look towards making the compilation of the project asynchronous as to not block other processes.

Finally, I checked that it had nothing to do with the front-end and back-end communication layer of Theia. The main reason was that the main Node.js thread was occupied. This problem was solved through the worker_threads module in the Node service.
