This implements the idea of automatically setting a content proc's
render root based on the render root enclosing the iframe that
points to it. There was a bit of cleanup in here that was a bit
tricky to extract from the core patch revolving around how we
use the Api(...) helper. This was to avoid the situation where
we use the Api(...) helper before our render root is initialized,
when we don't actually have to. I.e., when we just want the root
WebRenderAPI in all cases.
An alternative to this approach could be to fully built out the
WebRender transactions and just queue those up to be sent. However,
transaction building has various side effects which are committed
before the transaction is actually sent, so we would have to build
out some scheme for deferring those as well. This seemed simpler.

This commit attempts to lower the pain of modifying FrameMetrics.h.
It looks like most includes really only want ViewID or
ScrollableLayerGuid, so this commit factors them out into a separate
header. In the process FrameMetrics::ViewID is changed to
ScrollableLayerGuid::ViewID, which personally seems like a better
place for it now that we have RepaintRequest. Unfortunately that
requires a lot of places to be updated.
After this commit there are still a couple of major places that
FrameMetrics is included.
* nsDisplayList.h
* nsIScrollableFrame.h
* Layers.h
Those are going to be more tricky or impossible to fix so they're
not in this commit.

The majority of this patch is just plumbing. The interesting parts are
in WebRenderLayerManager and APZUpdater/WebRenderScrollData. Unlike
ClientLayerManager, which updates the FrameMetrics on the client side
and sends the modified version over to the compositor, this WR version
just sends the update info over to the compositor, which then applies
the update to the metrics saved in APZUpdater before triggering the
hit-testing tree rebuild.

When passing the transforms from nsDisplayTransform items down to the

so that the "ancestor transform" on the APZ side is correctly computed.

Due to an oversight in bug 1423370, the code I added was setting the
transform on a WebRenderLayerScrollData after initializing it, but the
initialization might have populated the transform. Thus the
transform-set that I added would have clobbered the transform. This
updates the code to combine the two transforms instead which avoids
the clobber.

The new struct is in LayersTypes.h, all the rest of the changes are just
replacing existing uint64_t instances with the new LayersId struct.
Note that there is one functional change, in
CompositorBridgeParent::DeallocPWebRenderBridgeParent, where we now
correctly convert the PipelineId to a LayersId before using it to index
into sIndirectLayerTrees, whereas before we were incorrectly just using
the mHandle part of the PipelineId.

This just adds the boilerplate that goes with the new protocol, without
adding any of the actual messages. The protocol is managed by PGPU, and
there will be one instance per compositor. The parent side lives on the
main thread of the GPU process, and the child side lives on the main
thread of the UI process. The protocol is only instantiated if the GPU
process is active.

Most of this patch is just mechanical changes, but note that this patch
now makes the mFlags in scrollbar-container nsDisplayOwnLayer instances
have one of the direction bits set. As a result, this requires changing
the implementation of nsDisplayOwnLayer::IsScrollThumbLayer().

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.

A basic sanity check here seems to produce the correct behaviour but I'm
not at all confident that this will always do the correct thing in more
complex cases or when perspectives are involved. However this is hard to
test and get working without the testing infrastructure up and running
so I'd rather land this simple code first and then dig into the more
complex cases once we have a way to catch regressions.

The three main changes in this patch are:
(1) Move the code to emplace_back a new WebRenderLayerScrollData to
after the display list recursion. This is necessary so that when we
empty the temporary mLayerScrollData stack into the final mScrollData
structure things end up in the right order.
(2) Maintain a stack of ASRs as we recurse so that when we are building
a given WebRenderLayerScrollData, we don't add scroll metadatas that
are already present on its ancestors.
(3) Compute the number of descendants created for each layer scroll
data item and record it, so that we can properly reconstruct the
shape of the tree.

Instead of the WebRenderLayerScrollData code knowing about all the
different display item types, it makes more sense to move this logic
into the display items.
In addition to avoiding dis-encapsulating the data from nsDisplayItem subclasses,
this makes it easier to handle two specific scenarios:
(1) the case where an nsDisplayItem A subclasses another nsDisplayItem B, but A
and B have different types returned by GetType(). Previously A and B would have
to be handled explicitly in the WebRenderLayerScrollData switch statements,
which doesn't scale well if new types are added. With the new approach the
virtual function is shared down from A to B and so takes care of it. This is
particularly relevant for types like nsDisplayOwnLayer which have a number of
subclasses.
(2) the case where a display item *might* have APZ-relevant information.
In this case the type of the item alone is not sufficient to determine
if we need to create a new WebRenderLayerScrollData for it. Instead, we
need to access specific state inside the display item. This is now
handled by the UpdateScrollData function returning true when passed
nullptr arguments, and replaces the switch statement in
WebRenderLayerManager that updated forceNewLayerData.

The semantics of the WebRenderScrollData structure is that the per-layer
structures form a tree with a single root node. When we build the data
structure from the display list, we are generating (for now) a flat
list. Therefore we need to synthesize a root node in order to make stuff
work as intended.

Until now WebRenderScrollData was only used with "layers" WR
transactions, but we want to use it with layers-free transactions as
well. As such, we need to allow collecting information from display items
instead of layers. This restructures the code a little bit to allow
that. This patch should not have any functional effect on the "layers"
codepath, but on the "layers-free" codepath it is now actually
populating some rudimentary data into the WebRenderScrollData before
sending it across. This will be fleshed out in future patches.

This also updates the WebRenderScrollDataWrapper function as it is meant
to be semantically equivalent to the LayerMetricsWrapper one, which
allows removal of a flag propagation.
