1455805 - Make "CSS" a namespace, not interface

Status: RESOLVED FIXED

(Core :: DOM: CSS Object Model, defect)

Description

[Boris Zbarsky [:bzbarsky]]

See https://github.com/w3c/csswg-drafts/pull/437

Compared to our current behavior this mostly manifests in typeof changing to "object" instead of "function" and the proto changing to Object.prototype instead of Function.prototype.

I suspect this is not a compat issue in practice...

Adding tests is a bit hard because of https://github.com/w3c/web-platform-tests/issues/7583
