Currently in ContainerState::SetupScrollingMetadata we call
ComputeScrollMetadata for every layer and for each ASR in the layer's
clip chain. If there are many sibling layers with the same clip then
this is largely wasted work.
This change makes us cache the most recently calculated result, and
only recalculate if the ASR or clip is different.
There was a small portion of ComputeScrollMetadata that must actually
be executed for every layer and ASR in its clip chain. This has been moved
to a separate function, ClipLayerToDisplayPort, that is still called
every time.

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.

Most of this change is just fiddling with function signatures so that they take
a LayerManager* instead of a Layer* (or in some cases, both). This allows
the WebRender codepaths to pass a WebRenderLayerManager* instead of having to
produce a Layer* which it doesn't have.

Find the scrollframe for a scrollbar thumb and use it to determine if the scrollthumb is an AGR, instead of recording if the associated scrollframe is active on a frame property during display list building.

Bug 1400459 devirtualized nsIAtom so that it is no longer a subclass of
nsISupports. This means that nsAtom is now a better name for it than nsIAtom.

This ensures that if the scroll event triggers style changes, they are
reflected on the same paint.
This is accomplished by having the refresh driver fire scroll events as
an explicit step after FlushType::Style observers and rAF callbacks, and
before the actual style flush.

nsIFrame::mClass is of type enum class nsQueryFrame::ClassID which is
a strict subset of the nsQueryFrame::FrameIID values. For a concrete
frame class, its FrameIID is the same numeric value as its ClassID.
