fix: Improve performance of the editor behavior in LG

[lei9444]

Description

In recoil and undo PR, the lg templates CRUD are removed from the worker, and some async functions were changed to synchronous.
It will take up a lot of cpu time during the parse processing, the main thread will be blocked and affect the editor input experience.

1. Revert some of the code about the async functions. feat: Add undo/redo for design page #3780
2. Add cache in the lg worker thread. We can use the parse result to improve the lg template CRUD performance. But the parse tree has Int32Array type, and can't be frozen by recoil. The composer will get the result without the parse result. So keep them in the worker thread.
3. Add debounced shell API for the editor. The copy, paste and move need to update lg before committing the snapshot to the undo stack. But the editor update can use debounced API to improve the performance.
