These changes are to support addition of a render blocking status field to Perfomance resource timing. Further details are available at w3c/resource-timing#327

For HTML side changes see whatwg/html#7979

(See WHATWG Working Mode: Changes for more details.)

I think it'd be better if this used the existing Request's render-blocking boolean. For that, I think you need to pass it with the request itself, and not when finalizing the response. Apologies for not catching that earlier.

I added Request's "render-blocking" as a boolean because I felt the multivalue enum is too Blink-specific.

Here, do we still want to put a multivalue enum on Request (like what Blink currently does), or just use the existing boolean?

Note that once @noamr's #1413 lands this will have to change somewhat significantly. And I suggest we land that first as it's a rather big change and it seems relatively straightforward to adjust this.

I've updated this to use Request's render-blocking boolean and also adjusted for #1413 changes

Looks okay modulo this nit. If this suggested change looks okay I'd be happy for @domenic to land this as I'll be away for the next couple weeks.
