Description

See discussion in https://github.com/avajs/ava/pull/3015. Certain Node.js flags stop worker threads from working. We should recognize that error (ERR_WORKER_INVALID_EXEC_ARGV) and print a useful error message so users know to disable worker threads in AVA.

Contributor guide

Research direction
Inspect the Node.js error `ERR WORKER INVALID EXEC ARGV` and modify the worker thread initialization code in AVA to catch this error and output a user friendly message suggesting to disable worker threads.
