When GDK_BACKEND is wayland, widget is not fully mapped during creating CompositorSession. During CompositorSession creation, GLContextProviderEGL::CreateForCompositorWidget() creates GLContextEGL, but we could not create valid EGLSurface. We could create valid EGLSurface when widget is fully mapped. CreateEGLSurfaceForCompositorWidget() is used for creating valid EGLSurface after widget is fully mapped.
