When we do the initial reflow, we remove nodes from the document if
we're printing the selection. If these operations cause one iframe to be
removed, for example, then we may get hit with an nsIWebProgress
notification synchronously, which may cause us to go through
MaybeResumePrintAfterResourcesLoaded too early (and thus twice), which
messes up our state.
The ideal solution would be to add us as a listener a bit later, but we
can't because we need to know whether we did load anything during the
initial reflow.
So instead of that, just avoid resuming print while we're doing the
reflow. We'll call MaybeResumePrintAfterResourcesLoaded a few lines
below.

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.

Otherwise my test fails intermittently on CI. We need to block on all
the load blockers because stuff like responsive images doesn't fire the
load directly but they do that as a micro task (blocking the load
event).

This is going to be useful for the new print preview UI, which is in a
doorhanger and thus much more likely to be less than the page size.
We (ab)use the existing print preview scaling mechanism. We only need it
after reflowing all pages, so this works.
This whole scaling mechanism is all-in-all not amazing, but the patch is
less gross than I initially thought. It's nice, actually.
We could put the new behavior behind a pref trivially, if that's wanted,
but I honestly thing this behavior is better even without the doorhanger
ui.

The fallback code in nsPrintJob::DoCommonPrint to create an nsIPrintSettings if
none is passed in is never used, since all callers pass a settings object.
However, to simplify future changes I'd like nsGlobalWindowOuter::PrintOuter to
stop creating and passing in its own default valued nsIPrintSettings object.
This patch makes the fallback code that DoCommonPrint calls do what
nsGlobalWindowOuter::PrintOuter does, and makes the latter stop passing in a
settings object.
This patch also removes nsIWebBrowserPrint.globalPrintSettings since
nsGlobalWindowOuter::PrintOuter was its only consumer.

The probes collect counts for:
- print preview open, and exit without print
- print dialog opened from print preview, and cancelled
- print dialog opened without print preview, and cancelled
- silent prints
- print target
- PDF file
- XPS file
- other (probably print to physical printer, but we can never be sure)
There is some overlap with the existing PRINT_* probes, but I think we should
keep those in place temporarily until we confirm that the new probes produce
numbers that are consistent with the old probes.
This patch only adds 'print target' probes for Windows and macOS.
I use nsDeviceContextSpec*::Init() to collect the 'print target' telemetry
because the way we initialize settings from prefs (and the way macOS works in
particular) make it difficult to reliably determine the target type earlier in
the print process for all possible entry points into the printing code.

This also removes nsPrintJob::mFallbackDocTitle since there really is no point
in blindly calculating it ahead of time when we will virtually never use it,
and even if there was there's no reason to store in on the nsPrintJob given
that we create a new nsPrintJob every time we print!

It calls `Document::FlushPendingNotification()` so that we should mark it
as `MOZ_CAN_RUN_SCRIPT`.
And the method calls it of `mDocument` and `mDocument` is never modified
after it's initialized. Therefore, we can move the initializer to the
constructor and make `RefPtr<Document>` to `RefPtr<Document> const`. Thus,
we can avoid unnecessary auto `RefPtr`.

nsPrintData::mBrandName never changes over the lifetime of a Firefox instance.
It is wasteful to have nsPrintData obtain and store it, since we can replace
an nsPrintJob's nsPrintData object multiple times over the lifetime of the
nsPrintJob and nsPrintJob is the only consumer.
