This PR mainly aims to solve the following problem. During the execution of the fsp.cp function, due to other file operations, the target directory of fsp.cp is created in parallel. The actual situation may be more complicated. Multiple file operations are executed concurrently, resulting in an error in the internal fsp.cp when calling mkdir, because the folder has been created by other file operations. In this case, you can actually ignore this error and continue with the subsequent file copying operation.
The relevant code is in lib/internal/fs/cp/cp.js.
destStat is empty here, it did not exist when checking the folder before.
I want to ignore the EEXIST error thrown by mkdir
