(Almost?) all other scrollbar performed scrolling goes through apz already (this effort was called "desktop_zooming_scrollbars").
This one mode was missed. It uses a repeating timer and setting the curpos attribute to trigger scrolling.
Unfortunately xul trees use this path as well, so we have to keep the old path around for them.
This makes one notable change in behaviour. Both before and after this patch single clicks on scrollbar buttons pass ENABLE_SNAP to the scroll from when they request scrolling (in nsScrollbarButtonFrame::HandleButtonPress). However for repeat scrolling when clicking and holding (which is handled by nsScrollbarFrame::MoveToNewPosition), before this patch the scrolling would not use ENABLE_SNAP. This is not super clear because MoveToNewPosition sets the curpos attributes, and then ScrollFrameHelper::CurPosAttributeChanged( would get called in response to that, and it would call ScrollToWithOrigin to the do scrolling, and it does not specify the snap mode, but the default is DISABLE_SNAP. This patch changes that so that we explicitly pass ENABLE_SNAP in MoveToNewPosition. It seems that this was likely overlooked (not hard to do when it's not clear like this) when adding snapping support. It makes sense to handle snapping the same way for single clicks and clicking and holding. If this turns out to be the wrong idea we can easily change it back.
Needs a test.

This is mostly a revert of the patch in bug 1425686 that removed the old
probe, but rebased to new code locations and clang-formatted. The histogram
entry is also updated with new bug numbers and fields.
The next patch will refine some of these telemetry recording points; the patch
is split into two for easier reviewing as this part is basically what landed
originally.

Along with a dependent struct DirectDrawInfo.
This allows nsImageRenderer.h and CanvasRenderingContext2D.h to
avoid including nsLayoutUtils.h.
For nsImageRenderer.h in particular, a forward declaration is
not sufficient as nsImageRenderer stores SurfaceFromElementResult
by value.
A couple of method definitions elsewhere are moved out of line
to keep things compiling without including nsLayoutUtils.h in
additional headers.

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()).

Initially this was going to be a simple cleanup: Remove some useless namespaces
here and there and so on, remove `using` statements from the header and so on.
But unfortunately, DOMIntersectionObserver.h (which is included in Element.h,
unnecessarily) ended up exposing `Element` unnamespaced to a lot of code, so I
had to fix that.

This patch creates new header, `mozilla/PresShellForwards.h`. It should have
all forward declarations of global class/struct in `nsIPresShell.h` and
`mozilla/PresShell.h`.
Additionally, this moves all `enum`s and `constant`s in them into the new file
with changing them to `enum class`es.
This will make other headers which require only specific types in the header
files not include them.

Moved mozilla::WidgetMosueEventBase::buttonType in MouseEvents.h to mozilla::MouseButton in EventForwards.h, and mozilla::WidgetMouseEventBase::buttonsFlag to mozilla::MouseButtonsFlag so that any referer in header files do not need to include MouseEvents.h only for referring them. Instead, they just need to include EventForwards.h. Now when MouseEvents.h is changed, the rebuild speed becomes faster.

Additionally, this patch makes `nsFrame.h` stop including `nsIPresShell.h`
and makes each users include `mozilla/PresShell.h` instead. So, this improves
rebuild performance of `nsIPresShell.h` (and `mozilla/PresShell.h` in the
future).
Note that due to `nsIFrame::PresShell()`, `mozilla::` prefix is necessary for
`PresShell` in a lot of classes which are derived from `nsIFrame` even in
`.cpp` files.

The DoMouseClick helper is also removed because no other caller can now pass a null aEvent. Other MouseClicked implementations are also updated since aEvent cannot be null, which was already the case.

This patch was generated automatically by the "modeline.py" script, available
here: https://github.com/amccreight/moz-source-tools/blob/master/modeline.py
For every file that is modified in this patch, the changes are as follows:
(1) The patch changes the file to use the exact C++ mode lines from the
Mozilla coding style guide, available here:
https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style#Mode_Line
(2) The patch deletes any blank lines between the mode line & the MPL
boilerplate comment.
(3) If the file previously had the mode lines and MPL boilerplate in a
single contiguous C++ comment, then the patch splits them into
separate C++ comments, to match the boilerplate in the coding style.
