Log Message:
-----------
Switch FontCache to use ThreadSpecific instead of ThreadGlobalData
https://bugs.webkit.org/show_bug.cgi?id=244919
Reviewed by Youenn Fablet.
ThreadGlobalData doesn't handle the case where we try to access it while it's
being shut down, and
the font code tries to do that.
ThreadSpecific should be faster, and safe for this case.
