If the compositor is destroyed whilst in the process of being
reinitialized, it is possible for a WebRenderBridgeParent to be
created in an already-destroyed state. In this case, we currently
avoid saving a reference to the WebRenderBridgeChild in
WebRenderLayerManager. However, this means that
WebRenderLayerManager's destruction does not cause the
WebRenderBridgeChild (and therefore the corresponding
WebRenderBridgeParent) to be destroyed, meaning its layer tree ID does
not get erased from the map.
This patch makes us unconditionally store a reference to the
WebRenderBridgeChild in WebRenderLayerManager, meaning it is correctly
destroyed and the layer tree ID is correctly erased from the map.

This patch adds plumbing to keep track of why we request frames to be rendered.
This information is then displayed in gecko profile markers on the renderer thread as well as in profiler HUD counters (See "Render reasons" in profiler.rs).

Before Win32k Lockdown, Canvas would ensure that it would get the fastest possible implementation by initializing
devices in content process before allocating persistent buffers for its backing.
However, with Win32k Lockdown it's no longer possible, as initializing Direct3D and Direct2D make Win32k calls that
crash the locked-down content process.
This issue is generally solved by Remote Canvas; however, Remote Canvas is disabled if the GPU process is disabled.
If that happens, the current behavior is to attempt to initialize hardware acceleration again, causing a crash when
Win32k Lockdown is in effect.
This patch changes the behavior so that the devices will not initialize if they are in a locked-down content process,
even if Remote Canvas is disabled. The effect is that Canvas will fall back to using Skia for everything.

Fix a bug where the display item cache was not being reused from
frame to frame with retained display list builders.
At the same time, make the capacity recycling on the display list
serialization arrays a bit more realistic.

When device reset happens, WebRender and WebRenderLayerManagers are re-created. In this case, pending transactions of nsRefreshDriver need to be cleared during destroying WebRenderLayerManager.

This will allow storing state in a display list builder struct
between different display list builds. In time, this will be used
to reduce the size of the serialized display list data, by only
sending delta changes to WR. The extra information made available
by sending deltas will then allow WR to more efficiently cache and
reuse information across different scene/frame builds.

This will allow experimenting with different representations of
the spatial tree (such as interning and/or providing stable
indices during display list building). It may also simplify
future changes to the public API to expose the spatial tree
directly.
As part of these changes, refactor how the debug representation
for the capture format is (de)serialized, to make it simpler to
add different payload vector types in future.

Move the extra_data to be a specific cache_data separate vec in
the display list payload.
This shouldn't change any functionality, but serves as a proof
of concept for future changes which will introduce several other
separated payload vectors.

When the ID namespace changes for a WebRenderBridgeChild, all bindings
from that namespace are now invalid. We already drop any outstanding
async animation holds on surfaces for recycling, but we still would try
to send out async resource updates that were already queued before the
namespace was changed. This patch forces us to drop those now defunct
transactions.
