fix: exclude missing dependencies from optimization during SSR

[ygj6]

Description

Optimized based on #4904 , fixed #4700 , and added test cases.

After I submitted the RP #4904 , I am going to add test cases according to the comment of @patak-js .

In the process of building test cases, I found a problem.

For testing, I did not add the script entry point in the index.html, it will be dynamically added during SSR.

First, if you import a missing dependency that contains multiple entries during SSR, it will execute server._registerMissingImport and build a server-based output.

Then, when the client imports the same missing dependency that contains multiple entries, it will directly consume the build result of the SSR stage. The build result is only applicable to the server, and importing on the client will cause an error.

In my opinion, there is no need to execute server._registerMissingImport during the SSR, because the build result is based on the server, and the optimized dependencies are for the client.

If there is anything missing, please remind me.
