Support for `fs.cp()`, fs.cpSync()`, `fsPromises.cp()`?

[rauschma]

The following three functions were added in Node.js v16.7.0 and are very useful because they enable you to copy directories recursively. AFAICT, mock-fs does not currently support them:

• fs.cp()
• fs.cpSync()
• fsPromises.cp()

ENOENT: no such file or directory, opendir 'a'

Unfortunately, these new apis use opendir internally.

Currently there is no way to support it, because nodejs has no intention to expose the new fs_dir binding for us to mock.
