fix: nest deps chunk cannot be loaded when optimizing deps in build mode

[ChuHoMan]

Description

fixes #13933
Align the load logic of optimizedDepsBuildPlugin with optimizedDepsPlugin. After loading the file from the cache, throw an exception if an error is encountered.

Additional context

As mentioned in the last context I provided in the issue. I noticed that the file field for the chunks in the .vite/deps/_metadata.json is processed with flattenId. But the chunk files generated by esbuild on the disk do not undergo the flattenId process. Is this behavior expected? If it's necessary to flatten the chunk filenames, would it be better to flatten the filenames when generating the chunk files with esbuild? However, at the moment, I'm not sure how to flatten the generated chunks.
