[vm] Use std::unique_ptr with Message

Message is a C++ type with a simple ownership model appropriate for
std::unique_ptr. This CL applies the following changes:

1. All uses of "new Message(...)" are replaced with
"Message::New(...)", which is effectively
"std::make_unique<Message>(...)". (The latter was only added in C++14,
but Dart still compiles in C++11 mode.)

2. All owning Message* are replaced with std::unique_ptr<Message>. The
notable exception is MessageQueue, which still uses raw Message*
internally to simplify the linked list handling.

3. All "delete message;" statements are removed.

4. Uses of "NULL" replaced with "nullptr" as necessary.
