Сковорода Никита Андреевич 709048134c buffer: backport new buffer constructor APIs to v4.x
This backports the new `Buffer.alloc()`, `Buffer.allocUnsafe()`,
`Buffer.from()`, and `Buffer.allocUnsafeSlow()` APIs for v4.

Some backported tests are disabled, but those are not related to the
new API.

Note that `Buffer.from(arrayBuffer[, byteOffset [, length]])` is not
supported in v4.x, only `Buffer.from(arrayBuffer)` is.
