[JSC] Add tests ensuring that extraMemorySize is monotonically increasing until full-collection happens https://bugs.webkit.org/show_bug.cgi?id=241832 rdar://95384643 Reviewed by Mark Lam. This patch adds tests ensuring that extraMemorySize is monotonically increasing until full-collection happens. If this assumption is broken, GC scheduling can be confused. And we crash with existing assertions. * JSTests/stress/array-buffer-transfer-should-not-reduce-extra-memory-size.js: Added.
