[ttml1] Specify implicit duration of <br>

palemieux has just created a new issue for https://github.com/w3c/ttml1:

== Specify implicit duration of <br> ==
Even though no timing vocabulary applies to the `<br/>` element (see https://github.com/w3c/ttml1/issues/310). an implicit duration needs to be specified otherwise the following is undefined:

```
<p dur="1s"><br/></p>
```

Suggest specifying that the implicit duration of `<br/>` follow the same semantics as anonymous spans since `<br/>` is expected to behave like an EOL.
