On Wayland with WebRender, RenderCompositorEGL creates headless context by using GLContextProviderEGL::CreateForCompositorWidget(), since GetNativeData(NS_NATIVE_EGL_WINDOW) returns nullptr. But we want to make hadless explicitly. But GLContextProviderEGL::CreateHeadless() and GLContextEGL::CreateEGLPBufferOffscreenContext() could not be used for it. They creates incompatible EGLConfig to egl window. Then we extends GLContextProviderEAGL::CreateForCompositorWidget() to handle this case. When CreateForCompositorWidget() receives null widget, it creates GLContext without surface of egl window.
