The size-adjust descriptor should not scale system fallback fonts.

When creating a system fallback font for a character on Mac, Blink
refers to the font platform data of the primary font. However, the
created system fallback font could be unintentionally scaled where
the size-adjust descriptor scales the primary font. To fix it, we use
the effective size of the font description instead.
