Move the font-size-adjust properties
Move the font-size-adjust properties

We don’t want these to apply to nta-tabular numbers or for print.

Move these properties, so that once the toolkit-font-stack is defined,
we can check to see if the $toolkit-font-stack variable is $NTA-Light
and if so, apply the font-size-adjust values.
