1. When creating a DocAccessibleParent for an embedded document in an OOP iframe, it's possible that the embedder accessible hasn't been set yet.
This can occur if the iframe is initially hidden.
Previously, we incorrectly set the document up as a top level document (e.g. tab document) in this case.
Now, we set up the document as top level in its content process, set up the proxy, etc.
The document will be added to its child document later when the embedder is set.
2. When setting the embedder accessible for an OOP iframe, check if the embedded DocAccessibleParent already exists.
This can happen if an iframe is hidden and then shown or an iframe is reflowed by layout.
If it already exists, add the embedded (child) document to its embedder.

impact.
I want to leave the repainting stuff to another bug to land separately, to track
potential (though I hope not!) perf regressions more easily.

In this patch, we add the propagation of the first party domain through
the tabContext while creating OOP browsers. In the window.open() case,
we will propagate the first party domain from the opener's browser parent.
And in the frame case, we will propagate it from the manager of the
browserBridgeParent of the OOP frame.

* This patch makes pages with the `OPENER_POLICY_SAME_ORIGIN_EMBEDDER_POLICY_REQUIRE_CORP` policy load into a special `webCOOP+COEP={pageOrigin}` remote type.
* Adds `E10SUtils.WEB_REMOTE_COOP_COEP_TYPE_PREFIX="webCOOP+COEP="`
* When a COOP process switch occurs and the target page doesn't have this policy, we pass a `preferredRemoteType="web"` into `E10SUtils.getRemoteTypeForPrincipal` ensuring that we correctly get a different `remoteType`
* E10SUtils.getRemoteTypeForPrincipal is changed such that `if preferredRemoteType.startsWith(WEB_REMOTE_COOP_COEP_TYPE_PREFIX)` we don't override it with `webIsolated={pageOrigin}`.
* `coop_header.sjs` is changed to also allow setting `Cross-Origin-Embedder-Policy` headers
* `browser_httpCrossOriginOpenerPolicy.js` is changed to test that pages are correctly opened in the correct remoteType process.

This flips the direction in which the BrowserBridge actor is generally created
such that it is generally created in the parent and sent down to a child
process.
This is done by making the decision about what kind of switch to perform in the
parent, and sending messages down to child processes async to orchestrate these
process changes.
Process launching is changed to use an async `MozPromise`-returning API in this
patch, though the actual process launching still occurs synchronously. A future
patch will enable performing async process launching through the
NewOrUsedBrowserProcess mechanism.
I know of at least a few timing issues which exist with the new logic,
especially around the state of the BrowsingContext during the process
transition. I decided to not try to fix all of these issues in this patch, as
many are complex and will require changing how we manage the lifecycle of
BrowsingContext substantially. I do, however, think that the new logic is more
reliable and has fewer timing issues than the previous logic.

This flag is only meant for window.open() stuff, so not relevant to iframes at
all.
This preserves the current fission behavior (which is quite broken) of always
showing scrollbars.
The way to control scrollbars for iframes (the scrolling attribute) is not
handled at all for Fission, I filed a bug and left a few FIXMEs.

Currently when checking if a window supports protected media it's up to the
caller interacting with a BrowserChild to check if a response is already
cached, to perform the check if needed, and to then set the cached response if a
call was made. This patch moves that logic internal to Browser child so that
callers need to only worry about interacting with a single function.
