`PresShell::GetRootScrollFrameAsScrollable()` is equivalent to
`PresShell::GetRootScrollContainerFrame()`.
In ScrollContainerFrame.h, `DecideScrollableLayer()` has two versions, one has
four parameters, and the other has five parameters with the fifth parameter
`aDirtyRectHasBeenOverriden` having a default value `nullptr`. When we switch
the caller from `nsIScrollableFrame` to `ScrollContainerFrame`, we need to
remove the default value for the fifth parameter to avoid ambiguity.

This fixes some intermittent that my previous patches introduce because
we don't reframe so often object or embed documents, and so the class
(which gets set on resize etc) isn't set.
The class is immutable in the object case so it's safe to just do this.

Clicking on the image toggles between "shrink to fit" and full size mode. However it also
resets the full zoom. So if the full zoom has been changed then a click can zoom in/out.
The full situation is complicated because you could be in "shrink to fit" mode (so the cursor
should be the zoom in cursor) and then increase the full zoom so that image is bigger than it
would be in fullsize mode so clicking would actually result in zooming out. I don't try to
resolve this. Instead I just let cursor be decided by the "shrink to fit"/full size state if
that's relevant, otherwise the fullzoom will determine the cursor.

By making image loading in <embed> and <object> behave more like when
an <iframe> loads an image, we can make sure that the synthetic
document generated is process switched if the image is cross
origin. This is done by making image loading in nsObjectLoadingContent
follow the document loading path.
We also make sure that we pass the image size back to the embedder
element to not get stuck with the intrinsic size.
To avoid named targeting being able to target these synthetic
documents, as well as showing up in `Window.frames` and being counted
in `Window.length`, we keep a filtered list of non-synthetic browsing
contexts for that use-case.
This feature is controlled by two prefs:
* browser.opaqueResponseBlocking.syntheticBrowsingContext
This triggers the creation of synthetic documents for images loaded
in <object> or embed.
* browser.opaqueResponseBlocking.syntheticBrowsingContext.filter
This turns on the filtering of synthetic browsing contexts in named
targeting, `Window.length` and `Window.frames`.

For both files, we've been keeping around an extra copy in
toolkit/themes/shared/media/ with 1-2 CSS rules related to presentation.
This was probably to allow XUL-style extensions and themes to override the
presentation, back when we supported that form of extension. But there's not a
good reason to have this separation anymore, so let's simplify and combine the
files of the same name.
This patch also removes one no-longer-esepcially-useful "N.B." comment (which
refers to a file that's now alongside the styles in question). This patch also
adds an explanatory comment to explain why we bother to set `color` for images
(which was initially not clear to me).

We need it to live in BrowsingContext instead of WindowContext, because
we need to preserve the zoom level across same-origin navigation.
It'd be nice if it only lived in the top BC, but that's not possible at
the moment because a lot of tests rely on zooming only iframes. Some of
them can be adjusted for scaling the top instead, but not sure it's
worth it's worth fixing them and moving the zoom to be top-only, as it'd
be a bunch of effort, and the complexity and overhead of propagating the
zoom is not so big.
The print-preview-specific code in nsContentViewer is from before we did
the document cloning setup, and it seems useless. I've tested print
preview scaling before and after my patch and both behave the same.
The rest is just various test changes to use the SpecialPowers APIs or
BrowsingContext as needed instead of directly poking at the content
viewer.
I named the pres context hook RecomputeBrowsingContextDependentData, as
more stuff should move there like overrideDPPX and other media emulation
shenanigans.
I also have some ideas to simplify or even remove ZoomChild and such,
but that's followup work.

The inclusions were removed with the following very crude script and the
resulting breakage was fixed up by hand. The manual fixups did either
revert the changes done by the script, replace a generic header with a more
specific one or replace a header with a forward declaration.
