As we are often converting from LayoutDevicePixel to LayerPixel types
in WebRenderDisplayItem code, I added a convenience overload of
RelativeToParent that takes a LayoutDeviceRect and returns a LayerRect,
even though this is a potential footgun if abused.

This adds a WebRenderScrollData class (which contains a list of
WebRenderLayerScrollData objects, among other things), and adds it to
the DPEnd/DPSyncEnd messages sent across PWebRenderBridge. These classes are
skeletons for now (more stuff will be added to them in future patches).

This is a largely uninteresting patch that just uses the DisplayListBuilder
directly. A wonderful cleanup patch will come after this. One of the more
interesting pieces is the use of PushBuiltDisplayList. This is needed for
handling empty transactions. See https://github.com/servo/webrender/pull/934
for more info.
This basically just splits the enum in two and does the necessary plumbing. The
worst part is that now DisplayItemLayers need to have two arrays of commands.
Fortunately, this will be going away in the future.
This makes it so we don't send the child side commands to the parent.
add width, height and format arguments in AddExternalImageId/AddExternalImageIdForCompositable()
turn to use AddExternalImageId() for TOpDPPushExternalImageId op.
send the Image/ExternalImages removing messages just after DPEnd()

Update PWebRenderBridge.ipdl to manage PCompositable.
Let WebRenderBridgeChild/Parent to implement CompositableForwarder and CompositableParentManager for compositable-op message.

The overall architecture here is that we add a new layers type, LAYERS_WR,
which can be used in place of client layers. The WebRenderLayerManager, in
the EndTransaction call, paints content into images and ships them over the
PWebRenderBridge to the compositor thread. The WebRenderBridgeParent code on
the compositor side talks to WebRender via the API in webrender.h.
