FrameProperties have Remove() and Delete() methods. If you call
Remove() you now own the result, therefore we should delete it.

Previously CreateWebrenderCommands would use GetLayerState to determine whether to use Webrender or
take the fallback path. GetLayerState would then under some cases call CanOptimizeToImageLayer()
which would get the image container using the appropriate flags for sync decoding.
Now nsDisplayBackgroundImage only uses CanCreateWebrenderCommands, which doesn't pass the correct
flags to image container, leading to reftest failures in some cases. This commit fixes that.

Currently, we use a simple merging algorithm, because the more
complicated ones didn't work.
This code won't actually be used until we do blob image invalidation
in a follow up.

We're not using named shared memory, and supporting only anonymous
shared memory allows using other backends that are more compatible
with preventing a process from accessing any shared memory it wasn't
explicitly granted (i.e., sandboxing).
Specifically: SharedMemory::Open is removed; SharedMemory::Create no
longer takes a name, no longer has the open_existing option which doesn't
apply to anonymous memory, and no longer supports read-only memory
(anonymous memory which can never have been written isn't very useful).
This patch also fixes some comments in what remains of SharedMemory::Create.

Currently we can only have one type of WebRenderUserData on an Item. We already
have a hash table of WebRenderUserData so it's not hard to include type in the
hash to support one per type.

This remotes the APZInputBridge interface over the PAPZInputBridge
protocol in the case of the GPU process, and makes the GPU process'
main thread act as the APZ controller thread in that process. If
there is no GPU process we continue as before and the APZInputBridge
interface implementation is the concrete APZCTreeManager instance
in the UI process.
The main changes in this patch are moving all the code associated with
these messages out of APZCTreeManager{Parent,Child} and into
APZInputBridge{Parent,Child}. APZCTreeManagerChild now returns an
APZInputBridgeChild instance via InputBridge(), instead of returning
itself. The SetControllerThread call in the GPU process is also updated.

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.

This is important because the RecvInitialize method in CompositorBridgeParent
is run via a sync IPC message, and so we are guaranteed that when return to the
caller in the UI process, the APZCTreeManager will have been created. This
ensures that when we create the APZInputBridge actors (which will happen on a
different top-level protocol, but be triggered after the sync RecvInitialize
is complete) we know that the concrete APZCTreeManager is ready for use.

This separates the methods that are used to deliver input events
synchronously over IPDL to the compositor; this interface will be
remoted over a new APZInputBridge IPDL protocol in future patches.
