[css-fonts] Avoid SECURITY_DCHECK failure with system font in animations

r885715 added CSSPendingSystemFontValue in order to handle system fonts
at parse time, deferring the resolution until computed-value time.

The problem was that animations weren't using StyleBuilderConverter, so
these CSSPendingSystemFontValue would remain unresolved in e.g.

  element.animate([{"font":"icon"}], {"duration": 1000});

Therefore, this patch makes CSSFontStretchInterpolationType and
CSSFontWeightInterpolationType use StyleBuilderConverter, just like
CSSFontVariationSettingsInterpolationType was already doing.

Bug: 1212321

TEST=external/wpt/css/css-fonts/animations/system-fonts.html

Some checks fail because the font-size of a system font interpolates
discretely. Worked well before r885715, I will fix it in a follow-up.
