[ttml2] base textAlign on CSS text-align property

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

== base textAlign on CSS text-align property ==
Part of umbrella #406 

Current semantic based on: XSL 1.1 §7.16.9 https://www.w3.org/TR/2006/REC-xsl11-20061205/#text-align
Current CSS snapshot version of this semantic: CSS 2.1 §16.2 https://www.w3.org/TR/2011/REC-CSS2-20110607/text.html#alignment-prop

The XSL spec references an earlier CSS spec to define the semantic. TTML also references XSL text-align-last, and requires it to be set to "relative". This has the same defined behaviour in CSS Text Module Level 3, and is presumably the normally implemented CSS behaviour.

Action to take: replace XSL spec reference with CSS snapshot spec reference.
