Reviewed by Tim Nguyen.

The MathML Core spec says that math-style and math-shift animate "by
computed value type". Their values being keywords means that they will
combine as discrete: https://www.w3.org/TR/web-animations/#by-computed-value.
Change animation type of math-style and math-shift to discrete.
Update expectations for math-* properties in animations tests.
