Pass through 'sbix' table

'sbix' table is used in Apple-style color font. By passing it through, Chrome on Mac, Linux, Chrome OS and Android
can use a Apple-style color font when served as a web font.

I didn't use |#if !OS(WINDOWS)| (Windows is the only platform where Chrome does not support
sbix) following the precedent of other tables.

TEST=Layout tests to be added.

LGTM. Are you planning to follow up on this one?

FWIW latest Windows supports sbix, though Blink probably doesn't support that
yet.
