Dynamic import module build problem

[sanyuan0704]

Describe the bug

Dynamic import module cannot seperate source code and dependencies code after build.Inside vite, only the dependencies of non-dynamically imported modules will be packaged into the vendor. But for dynamically imported modules, their dependencies will be packaged with the application code, resulting in a decrease in the cache hit rate.
