FileReader should not prevent entering the back/forward cache
https://bugs.webkit.org/show_bug.cgi?id=203106

Reviewed by Geoffrey Garen.

Source/WebCore:

FileReader should not prevent entering the back/forward cache. To support this,
its implementation now uses a SuspendableTaskQueue to dispatch events.
