RenderThread::PushPendingRemoteTexture() notifies pending RemoteTextures to RenderThread. And RemoteTextureMap::CheckRemoteTextureReady() is used for checking if a RemoteTexture is ready. If the RemoteTexture is not ready during the function call, callback will be called when the RemoteTexture becomes ready.
RemoteTextureMap::GetExternalImageIdOfRemoteTextureSync() is changed to RemoteTextureMap::GetExternalImageIdOfRemoteTexture() and wait of RemoteTexture ready in the function is removed. The wait of RemoteTexture ready is done by the callback of the CheckRemoteTextureReady().
