chore: move mfs and multipart files into core (#2811)

BREAKING CHANGE:

When the path passed to `ipfs.files.stat(path)` was a hamt sharded dir, the resovled
value returned by js-ipfs previously had a `type` property of with a value of
`'hamt-sharded-directory'`.  To bring it in line with go-ipfs this value is now
`'directory'`.
