The order of these calls is important. When the Isolate is disposed,
it may still post tasks to the platform, so it must still be registered
for the task runner to be found from the map. After the isolate is torn
down, we need to remove it from the map before we can free the address,
so that when another Isolate::Allocate() is called, that would not be
allocated to the same address and be registered on an existing map
entry.

As V8 is moving towards built-in CppHeap creation, change the
management so that the automatic CppHeap creation on Node.js's end
is also enforced at Isolate creation time.
1. If embedder uses NewIsolate(), either they use
IsolateSettings::cpp_heap to specify a CppHeap that will be owned
by V8, or if it's not configured, Node.js will create a CppHeap
that will be owned by V8.
2. If the embedder uses SetIsolateUpForNode(),
IsolateSettings::cpp_heap will be ignored (as V8 has deprecated
attaching CppHeap post-isolate-creation). The embedders need to
ensure that the v8::Isolate has a CppHeap attached while it's
still used by Node.js, preferably using v8::CreateParams.
See https://issues.chromium.org/issues/42203693 for details. In
future version of V8, this CppHeap will be created by V8 if not
provided, and we can remove our own "if no CppHeap provided,
create one" code in NewIsolate().
