Support V8 --async-stack-traces in NODE_OPTIONS#35627

Is your feature request related to a problem? Please describe.
I would like set the V8 --async-stack-traces option through the NODE_OPTIONS environment variable.

Describe the solution you'd like
NODE_OPTIONS="--async-stack-traces" node should not throw the Error --async-stack-traces is not allowed in NODE_OPTIONS

Describe alternatives you've considered
setting --async-stack-traces as a command line argument is not possible in controlled environment like AWS Lambda (which only support NODE_OPTIONS)

    This flag is enabled by default in V8. You do not need to pass it.

    Ok, thanks. Then it seems to be a problem with my code or with the AWS SDK.
