recursive option for fs.rmdir

[silverwind]

fs.mkdir gained a recursive option in 10.12 (providing alternative to the mkdirp module) and I think the popularity of the rimraf module speaks for itself that there is very high userland to justify having it on fs.rmdir and it's variants too.

Examples of other languages implementing similar functionality are golang's os.RemoveAll or python's shutil.rmtree.

If we are to implement this in JS, we can use the withFileTypes of fs.readdir to skip on stat calls which will outperform the current implementation of rimraf.
