Records where a material was created and last changed, so that the debug build can report them
when a material property is changed without a subsequent call to [Material#update](https://api.playcanvas.com/engine/classes/Material.md#update).

```ts
const TRACEID_MATERIAL_UPDATE: "MaterialUpdate" = 'MaterialUpdate'
```
