Expose internal stream utils

[ronag]

I think it would be useful for the ecosystem if we exposed some of our stream utility function from https://github.com/nodejs/node/blob/master/lib/internal/streams/utils.js.

In particular:

isReadableNodeStream(obj)
isWritableNodeStream(obj)
isNodeStream(obj)
isDestroyed(stream)
isWritableEnded(stream)
isWritableFinished(stream, strict)
isReadableEnded(stream)
isReadableFinished(stream, strict)
isReadable(stream)
isWritable(stream)
isFinished(stream, opts) 
isClosed(stream)
isDisturbed(stream)

Additionally maybe some that we don't have yet:

isAborted(stream)

One problem I see atm is the confusion/ambiguity between web and node streams, e.g. in #39628 we are working on isDisturbed which works no both node and web streams.
