Store script's LuaListener in userdata in lua_State's Registry.

Instead of deriving LuaListener from LLInstanceTracker with an int key,
generating a unique int key and storing that key in the Registry, use new
lua_emplace<LuaState>() to store the LuaListener directly in a Lua userdata
object in the Lua Registry.

Because lua_emplace<T>() uses LL.atexit() to guarantee that ~LuaState will
destroy the T object, we no longer need ~LuaState() to make a special call
specifically to destroy the LuaListener, if any. So we no longer need
LuaState::getListener() separate from obtainListener().

Since LuaListener is no longer an LLInstanceTracker subclass, make
LuaState::obtainListener() return LuaListener& rather than LuaListener::ptr_t.
