JS wrapper of target in ResizeObserverEntry/ResizeObserver shouldn't get collected ahead https://bugs.webkit.org/show_bug.cgi?id=197457 Patch by Cathie Chen <cathiechen@igalia.com> on 2019-06-04 Reviewed by Ryosuke Niwa. Source/WebCore: Add JSCustomMarkFunction to make sure JS wrappers wouldn't be collected when JSResizeObserverEntry live. For ResizeObserver, if targets are removed, it will get fired for the last time. We also need to keep these JS wrappers live. So add these targets to a GCReachableRef list once they're observed. Add element-leak.html to test the targets with `entry.target.myEntry = entry` could be released properly.
