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 * web-platform-tests/wpt#17802 * web-platform-tests/wpt#17909 * web-platform-tests/wpt#18543 * web-platform-tests/wpt#20116 * web-platform-tests/wpt#22358 Closes #4732. Closes #5122. Closes #5444. Follow-up: #5435.

These are two simple ImageBitmap tests. As far as I can tell Firefox does not support messaging ImageBitmap around. Chrome does, but something goes wrong with shared workers. Even if I change
bitmapto something like"x"Chrome times out the test, whereas that will work in Firefox.
