[core] Make include_log_monitor configurable in the ray start command

[kevin85421]

Why are these changes needed?

In #48642, the user creates two Ray nodes in the local environment, causing both the head and worker nodes to launch a log monitor process. As a result, the logs are printed in the driver process twice.

This PR makes --include-log-monitor configurable, allowing users to launch a log monitor process only when starting the head node, preventing duplicate logs.

# test.py
import ray

@ray.remote
def foo():
    print('hello')


if __name__ == '__main__':
    ray.init()
    handle = foo.remote()
    ray.get(handle)
