The pointer used to hold an incoming dynamically loaded module's
node::node_module structure needs to be thread-local. So far this was
done with uv_key_set() and uv_key_get(). The language now supports
the thread_local keyword which makes implementing this a lot cleaner.

Just node_module*, no struct (see lines above), and the = nullptr isn't strictly necessary.

👍 on the node_module*, but I'd like to keep the initialization because we do a

CHECK_NULL(thread_local_modpending);

later on, and I'm not 100% sure that these variables get initialized on every platform.

OK, looks like the variable oughta get zeroed out: https://en.cppreference.com/w/cpp/language/initialization#Static_initialization

Let's see if rebasing makes a difference for the CI.
