perf(ngcc): do not copy files that have been processed (#40429) 

When using the `NewEntryPointWriter`, we must copy over all files from the
entry-point bundle to the new entry-point. But since we are going to
write out the modified files directly, there is no need to copy those.
This commit skips copying the files that have been modified.
