deps: cherry-pick 0483e9a from upstream V8

Original commit message:

    [api] Allow embedder to construct an Array from Local<Value>*

    Currently to obtain a v8::Array out of a C array or a std::vector,
    one needs to loop through the elements and call array->Set() multiple
    times, and these calls go into v8::Object::Set() which can be slow.
    This patch adds a new Array::New overload that converts a
    Local<Value>* with known size into a Local<Array>.
