Before this patch, in non-fission mode, we cache storage access granted result
in the top-level window so we don't have to iterate all the browsing contexts
in the same tree while syncing the storage permission granted decision.
However, since we plan to rely on the current update mechanism to sync
mHasStorageAccess flag for different documents in the same tab (instead of using
the syncing mechanism of permission manager), we will eventually need to iterate
the browsing context tree to find all the documents to sync. Base on this,
we no longer have to maintain different method for fission and non-fission.
In this patch, we store the permission granted result in the inner
window instead of using permission key and store the key in the top-level
window.

This also requires changing the EffectCompositor to allow animations in print

This patch persists the CrossOriginEmbedderPolicy on the Document and
WindowContext.
The WindowContext's embedder policy is set in
WindowGlobalActor::BaseInitializer by either adopting the policy of the HTTP
channel that loaded the document, or in WindowGlobalChild::OnNewDocument
by inheriting the one from the browsingContext's windowContext.

This removes processing of HTTP Public Key Pinning headers, remotely modifying
pinning information, and using cached pinning information, all of which was
already disabled in bug 1412438. Static pins that ship with the browser are
still enforced.

THis should continue allowing users to zoom out in RDM mode, or any time that
we are respecting the meta-viewport tag. It's only when we don't respect the
meta-viewport tag that we disable zooming out past initial zoom.

This removes the need for FrameForPointOptions::IsRelativeToLayoutViewport,
and makes sure each call site of these functions indicates whether the
input point/rect is in visual or layout coordinates.
Several call sites were passing in layout coordinates without setting the
IsRelativeToLayoutViewport flag, which this patch corrects.

This "upgrades" various nsLayoutUtils functions which take as inputs
a set of coordinates and a frame that the coordinates are relative to,
to accept a RelativeTo object instead of a frame.
Most of the patch is just dumb propagation, but the few places where
we use an explicit ViewportType::Visual are important. There are
probably a few other places I've overlooked, but this seems to cover
the important ones that come up commonly.
There are undoubtedly other functions into which we can propagate
RelativeTo, in this patch I've propagated it as far as necessary
for my needs in this bug (mainly GetTransformToAncestor() and
GetEventCoordinatesRelativeTo()).

We set opener policy from the channel of the new document when creating a
WindowGlobalChild. However, we need to check if it's crossOriginIsolated even
when the WindowGlobalChild hasn't been created for the new inner window in some
cases.
To avoid checking the unset value of opener policy from the BrowsingContext,
this patch moves the setting the opener policy right before creating a native
global for a new inner window. So that the value of opener policy should always
be correct when validating it (IsSharedMemoryAllowed).

This provides web compatability with Chrome's interpretation of the spec at
https://drafts.csswg.org/css-device-adapt/#user-zoom-desc. This changes makes
us treat "the user cannot interactively change the zoom factor" as inclusive
of ANY method of the user agent changing zoom levels, regardless of whether or
not the user initiated an action.
So, in addition to preventing things like double-tap-to-zoom and pinch-zoom,
this change prevents zoom changes to fit all content into the viewport, or to
maintain visible content proportionality if the viewport is resized dynamically.
This also adds an assert to cases where Document::GetViewportInfo returns a
viewport with a non-positive scale factor that it also sets the auto scale
flag.
This also adds a tentative web-platform test.

In Document::HasStorageAccess(), we try to get the top-level document.
To check if the document is first-party to the top-level document. But,
this won't work for Fission since the top-level document could be
out-of-process.
In this patch, we use broswing context to get the top-level principal to
test if the document is thrid-party. If we cannot get the top-level
outer window, the top-level document should be cross-origin. So, we know
the answer. If the top-level document is available, we check the
principal to see if the document is first-party.
