  Try loading fonts with CTFontManagerCreateMemorySafeFontDescriptorFromData in Lockdown Mode.

https://bugs.webkit.org/show_bug.cgi?id=267948

rdar://121280542

Reviewed by Brent Fulgham and Chris Dumez.

Most Web fonts are not parsed in Lockdown Mode. On systems that provide an
alternative, safe font parser, try to use that font parser. Whether to enable
a fallback font parser is controlled by the LockdownFontParserEnabled setting,
added in "testable" status.
