Remove WebKit::Platform dependencies from cc

This removes all dependencies on the static WebKit::Platform pointer from cc.
The biggest change is implementing cc::Thread on top of base::MessageLoopProxy
instead of WebKit::WebThread. For the main thread cc::Thread simply binds to
the current thread's MessageLoopProxy. For the impl thread, the bindings layer
(specifically webkit/compositor_bindings/web_compositor_impl) extracts the
MessageLoopProxy out of the passed in WebThread.
