FontFace: Reject with SyntaxError when immediate buffer source fails to parse
https://bugs.webkit.org/show_bug.cgi?id=312167
rdar://174669738
Reviewed by Brent Fulgham.
Per the CSS Font Loading spec §2.1, when a FontFace is constructed
from a BufferSource and the data fails to parse as a font, the loaded
promise should reject with SyntaxError. NetworkError is reserved for
URL-based fetch failures (§2.2).
