Emitting 'close' before 'finish' on a Writable should result in a premature close error.

I'm hoping this does not cause problems such as #29699. Which was on the Readable side.

LGTM but if there is a risk this could break things, we should do some additional verification before landing and/or possibly consider semver-major

@jasnell's comment raised my concern as well, I've made this check a little less strict. PTAL

I would recommend this is semver-major as well to ensure no breakage in ecosystem. These kind of changes seem to be a bit sensitive.

@ronag should we land this on 12.x? It lands cleanly, just want to make sure if we need to backport a bunch of streams stuff it isn't partially done

My recommendation is not to land this on 12.x. It's not semver major but it slightly changes the behavior.
