My fix in #25030 was buggy, I forgot to pass the `byteOffset` and `byteLength`. Whoops. I also discovered that fs.read was not respecting the `offset` argument, and we were constructing a new `Buffer` for the callback instead of just passing the original one (which is what node does, and the @types/node definitions also indicate the callback should get the same type). Fixes #25028.
