Andreas Kling 1ab23e67e9 LibJS: Use an intrusive list for cached typed array views ...

Track typed array views with cached backing-store pointers through an
intrusive list instead of a WeakHashSet. The cache only needs linear
enumeration when an ArrayBuffer detaches, and IntrusiveList::append()
already deduplicates a view when initialization refreshes its cached
pointer more than once.

Unlink cached views from TypedArrayBase::finalize(), before cell
destruction, so dead views do not leave list nodes behind. Also unlink
when a view can no longer cache its data pointer.
