Web Inspector: use maxJSObjectId that is provided by back-end.

Web Inspector: use maxJSObjectId that is provided by back-end.
https://bugs.webkit.org/show_bug.cgi?id=82451

Summary view can filter objects in snapshot. It uses maxJSObjectId for this.
There was no such field in the profile header at the
moment but I've landed a patch in downstream.
