This patch makes the CanvasManagerChild creates/manager the ActiveResourceTracker instead of the WebRenderBridgeChild. Since PCanvas is now managed by PCanvasManager, and ActiveResourceTracker is only used by the PCanvas recording plumbing, we need it on every thread that the CanvasManagerChild can be created.
