fix: nodejs#42523 Problem: If no platform worker exists, Node.js doesn't shut down when background tasks exist. It keeps waiting in `NodePlatform::DrainTasks`. Observation: It seems that Node.js used to use V8's `DefaultPlatform` implementation, which chooses a suitable default value in case that `--v8-pool-size=0` is given as a command-line option. However, Node.js currently uses its own v8::Platform implementation, `NodePlatform`. It doesn't have the logic to handle the case. I referred to nodejs#4344 to track the issue.

It doesn't terminate when any pending V8 tasks exist if no thread is in the pool. This allocates one thread at least for V8's background tasks if `--v8-pool-size=0` is given as a CLI option.

Version
v18.0.0-pre
What steps will reproduce the bug?
Run a file including the above script with
--v8-pool-size=0
cli option.How often does it reproduce? Is there a required condition?
I guess it always occurs when running any script using worker_threads with
--v8-pool-size=0
.What is the expected behavior?
What do you see instead?
