Bug 1594331 - Port bug 1592369: rewrite consumers of the deprecated "left" and "right" align values to "start" and "end". r=khushil

* align="left" -> align="start"
* align="right" -> align="end"
* setAttribute("align", "left") -> setAttribute("align", "start")
* setAttribute("align", "right") -> setAttribute("align", "end")

```
