  Add WorkerClient for WebCore to access WebKit from worker threads, and use it to create a RemoteRenderingBackendProxy per-thread
https://bugs.webkit.org/show_bug.cgi?id=244828

Reviewed by Kimmo Kinnunen.

Creates a new interface class WorkerClient (which implements GraphicsClient), for accessing WebKit graphics APIs from a worker thread. Adds an implementation
of this in WebWorkerClient.

Allocates an instance of (Web)WorkerClient for every dedicated and shared worker, and makes it available via WorkerGlobalScope.

WebWorkerClient creates a dedicated GPUProcessConnection and RemoteRenderingBackendProx for each worker thread/instance, and uses this to create
RemoteImageBufferProxys that are safe to use on that worker thread.
