font-synthesis: Avoid synthetic oblique for variable fonts in @font-face
https://bugs.webkit.org/show_bug.cgi?id=316289
rdar://178698772
Reviewed by Brent Fulgham.
Same as https://commits.webkit.org/314814@main but for the oblique/italic axis:
a variable font with a slnt or ital axis already produces the closest available
slope, so synthetic obliquing on top is wrong. Only suppress synthesis when the
font-style descriptor is auto, letting the variable axis own the slope. Also fix
CachedSVGFont to compute synthetic bold/italic instead of hardcoding them false.
