[ttml2] Clarify application of unicodeBidi and direction on p (#1212)

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

== Clarify application of unicodeBidi and direction on p ==
Arising from #1211 clarify the application of unicodeBidi and direction on the p element (only).

Suggest matching [CSS text direction](https://www.w3.org/TR/css-writing-modes-3/#text-direction).

* direction sets the paragraph embedding level
* unicodeBidi values `plaintext` and `bidi-override` have specific effects
* other values have no specific effect
