`fs.cp()` should support copy-on-write operation if the underlying platform supports it
What is the problem this feature will solve?
fs.copyFile() supports copy-on-write operation if the underlying platform supports it by passing a mode flag. This behavior was added in a16d88d.
However, fs.cp(), fs.cpSync(), and fsPromises.cp() does not support its behavior and there are not any flag to change to it.
What is the feature you are proposing to solve the problem?
fs.cp(), fs.cpSync(), and fsPromises.cp() should have a way to enable copy-on-write behavior if the platform supports it.
What alternatives have you considered?
I had opened the #47074 once but it was withdrawn by that it should sort with the behavior of fs.copyFile() as opt-in behavior.
