deps: V8: cherry-pick cca9ae3c9a

Original commit message:

    Remove recursion from NeedsCheckHeapObject.

    We use the predicate NeedsCheckHeapObject in the compiler frontend to
    determine whether we can skip introducing CheckHeapObject nodes. But
    this predicate would also walk up the graph in case of Phis, which can
    result in really long compilation times (on the main thread). In the
    report in https://github.com/nodejs/node/issues/27667, the compiler
    frontend alone took around 4-5mins of main thread time for a single
    function. With this patch the time goes down to 4-5ms.
