[ttml2] Add TTML feature(s) for rw/rh <length> units

spoeschel has just created a new issue for https://github.com/w3c/ttml2:

== Add TTML feature(s) for rw/rh <length> units ==
The `rw` and `rh` units can be used in [`<length>` expressions](https://w3c.github.io/ttml2/#style-value-length) and were added by TTML2. However they are currently not covered by a respective TTML feature - in contrast to the other allowed units of `<length>` (e.g. `#length-em` for the `em` unit).
