[Bug] Missing functions in the fslib

[arcanis]

Describe the bug

The fslib is missing the following list of functions from the fs module:

• [ ] cp (experimental)
• [x] fchmod https://github.com/yarnpkg/berry/pull/4466
• [x] fchown https://github.com/yarnpkg/berry/pull/4801
• [ ] fdatasync
• [ ] fsync
• [x] ftruncate https://github.com/yarnpkg/berry/pull/4477
• [ ] futimes
• [ ] lchmod
• [ ] lchown
• [x] mkdir recursive: true needs to return the created directory. https://github.com/yarnpkg/berry/pull/4462
• [ ] readv
• [ ] rm
• [ ] writev
• [x] https://github.com/yarnpkg/berry/pull/4475

To fix that, the best course of action is to add them in the FakeFS interface, see what are all the type errors that appear, and implement the functions in all the fs implementations (it's fine to just mark the ZipFS ones as unimplemented for now, although they shouldn't be too hard to implement anyway).

Good night, I am and a friend we are starting to contribute with free software and contribute to this edition

I've updated the OP with the currently missing functions.

What's the status on this issue? These functions still need implementing?
