Per discussion in whatwg/html#4732 the SharedArrayBuffer constructor is not always going to be exposed so tests need to use COOP+COEP or new WebAssembly.Memory({ shared:true, initial:numberOf64KBPages, maximum:numberOf64KBPages }).buffer to get an instance. Most of the html/ matches should be good already. IndexedDB/ matches, but doesn't have any test.

Okay, so I think this can be closed once these are reviewed/landed:

Should be straightforward to review. @syg are you up for it or someone else in V8? Maybe @mathiasbynens?

Add the cross-origin isolated primitive
50ebcb4 
A top-level navigation response with Cross-Origin-Opener-Policy set to same-origin and Cross-Origin-Embedder-Policy set to require-corp will create a cross-origin isolated browsing context group. And all agent clusters therein will be cross-origin isolated as well (shared and service workers can still not be, as they sit on the side).

This change also:

* Gates SharedArrayBuffer exposure behind that primitive for web compatibility reasons.
* Gates SharedArrayBuffer sharing behind that primitive.
* Exposes it through self.crossOriginIsolated.
* Makes document.domain return before it mutates the origin.
* Makes agent clusters keyed on origin.

Tests:

* web-platform-tests/wpt#17719
* web-platform-tests/wpt#17760
* web-platform-tests/wpt#17761

Closes #4732. Closes #5122. Closes #5444.
