Bug 1878199 - patch 2 - If the FontFaceImpl has a user-font entry, hold its lock during Add/Remove font-set operations. a=dmeehan This should fix the intermittently-reported race here, by ensuring that access into the FontFaceImpl from GetUserFontSets(), called by the main thread, cannot race with changes being made by the AddFontSet()/RemoveFontSet() methods. (If the FontFaceImpl doesn't have an mUserFontEntry yet, then these methods don't need to lock, as only the owning thread will be touching it.)
