This centralizes our print and preview setup in nsGlobalWindowOuter so
that we never re-clone a clone, and so that we reuse the window.open()
codepath to create the browsing context to clone into.
For window.print, for both old print dialog / silent printing and new
print preview UI, we now create a hidden browser (as in with visibility:
collapse, which takes no space but still gets a layout box).
* In the modern UI case, this browser is swapped with the actual print
preview clone, and the UI takes care of removing the browser.
* In the print dialog / silent printing case, the printing code calls
window.close() from nsDocumentViewer::OnDonePrinting().
* We don't need to care about the old print preview UI for this case
because it can't be open from window.print().
We need to fall back to an actual window when there's no
nsIBrowserDOMWindow around for WPT print tests and the like, which don't
have one. That seems fine, we could special-case this code path more if
needed but it doesn't seem worth it.

Checking for an nsISHEntry doesn't work anymore with session history in the
parent. For that we can check that the loading session history info's
mIsLoadFromSessionHistory is true. If there is no loading session history info
we can fall back to the old way of checking for a non-null nsISHEntry (which
will only ever be true if session history in the parent is turned off).

There is the same information exposed in DocShellLoadStateInit.
And we don't really need to query user action from BrowsingContext, this
information would be carried in `nsDocShellLoadState`.

SessionHistoryEntry::MaybeSynchronizeSharedStateToInfo call is a tad controversial, but
something like that is needed for the cases when the actual value lives in the SHEntrySharedParentState.

This patch enables sandboxed srcdoc loads to take place via DocumentChannel,
and adds mechanisms for enabling unsandboxed ones.
Both unsandboxed srcdoc, and in subsequent patches, about:blank, loads require
that the triggering principal and the principal to inherit point to the same
instance if the load takes place in the same process as where we are inheriting
those principals from. We save those principals on a target browsing context before
we load the URI, and later, when we are deserializing LoadInfoArgs into
LoadInfo in the content process, we retrieve the saved principals if the
current load identifier of the target BC matches the load identifier saved
along with the principals.
We also need to make sure that during a process switch for about:srcdoc load,
we don't use the original URI for about:srcdoc to determine the remote type and
instead we use channel's result principal.

This changes the set of types which can be passed as the second argument to
do_QueryActor to ones which can be unambiguously converted to a JSActorManager,
and combines nsCOMPtr_helper implementations.

With fission enabled, walking the docshell tree to find unloaded
parents would stop at the first OOP parent. Instead we now walk
the `BrowsingContext`/`WindowContext` tree. To still check parents
which are OOP, we take advantage of the fact that a parent
`WindowContext` will no longer be the current `WindowContext` if
the parent was unloaded. For in process docshell's we additionally
check the docshell directly.
