When WebRender creation is failed, WebRender is disabled in gecko. There is a case that WebRenderBridgeParents exist when WebRender is disabled. To handle this, gecko needs to rebuild all CompositorSessions.
There is also a problem related to gfxVars::UseWebRender on compositor thread. If e10s is enabled, but no-gpu process(default on linux and mac), gfxVars::UseWebRender change is soon notified by compositor thread tasks. If WebRender creation failure happens at 2nd WebRender creation, several WebRenderBridgeParents for 1st WebRender could exist. IPC messages from WebRenderLayerManager are normally async, then there is a chance that the WebRenderBridgeParents receive the messages after the gfxVars::UseWebRender change. Further the gfxVars::UseWebRender change in content process could be delayed than WebRenderBridgeParents, then content process does not have a way to stop sending PWebRenderBridge IPC until the change of gfxVars::UseWebRender is received. WebRenderBridgeParent related tasks handle the message, but some tasks are done based on gfxVars::UseWebRender. At this time, gfxVars::UseWebRender returned false on compositor thread, then it cause unexpected result for WebRenderBridgeParent and WebRender. To addres this inconsistent situation, WebRenderBridgeParent related tasks on compositor thread stop to use gfxVars::UseWebRender.
When empty transaction in layers free mode, we don't rebuild whole
display list. But the canvas content will be updated and send the
content to parent by CanvasClient. We need some mechanism just like
async video which can update the content without rebuild the dl. But
CanvasClient doesn't use ImageBridge at all. So I slightly modify
AddPipelineIdForAsyncCompositable to let it support the Compostiable
either store in ImageBridge or WebRenderBridgeParent.

The notification is sent via GeckoContentController, PAPZCTreeManager if
necessary (to go from the GPU process to the parent process), and the
observer service.
Naturally, the notification is not sent in the case where it's browser.xml
that initiates the shutdown.

The messages are routed through nsITabParent, nsIWidget, and IAPZCTreeManager
(the latter possibly remoted via PAPZCTreeManager if out-of-process compositing
is used).

We have a minimum requirement of VS 2015 for Windows builds, which supports
the z length modifier for format specifiers. So we don't need SizePrintfMacros.h
any more, and can just use %zu and friends directly everywhere.

CompositorManagerChild::mCanSend is cleared in ActorDestroy but that
often comes in too late and after ContentChild::RecvReinitRendering
which reinitializes the singleton. For now, just remove the assert so
that we no longer trigger false positives in the content process after
the GPU process crashes.
The patch removes CompositorBridgeParentBase::GetAnimationStorage and CrossProcessCompositorBridgeParent::GetAnimationStorage, and remove the "aId" parameter to CompositorBridgeParent::GetAnimationStorage, since it's only ever called with "0" as the argument.
This requires:
- Moving the constructors of ProfilerMarkerPayload and its subclasses into the
.h file so they are visible even when ProfilerMarkerPayload.cpp isn't
compiled.
- Similarly, using a macro to make StreamPayload() a crashing no-op when the
profiler isn't enabled. (It is never called in that case.)

The patch fixes a problem on windows. Before the patch, there was a case that moved tab was not re-rendered. When WebRenderBridgeParent reveived obsolted transaction, DidComposite() was not returned to a client side. It stopped nsRefreshDriver to trigger a next transaction.
When the tab move happens, related non-root WebRenderBridgeParent is updated as to render to different webrender instance. webrender does not support of sharing resources and keys yet. Then when the tab move happens, the patch just removes all keys and resources that belongs to previous webrender. Ideally all resources that belong to WebRenderBridgeParent should be reallocated in an update webrender. But the patch does not do it, instead it just request WebRenderBridgeChild to re-allocate all resources again for simplicity. Performance improvement will happen in a future patch.
This patch support only tab move that uses only raw data external images. Support of native texture external images will happen in a future patch.
