  • Do not pass a milliseconds::max() timeout that will overflow when converted
    to nanoseconds
  • Avoid holding the task_queue_mutex_ while calling glfwWaitEventsTimeout
  • Use a signed type to hold the difference between a task's timestamp and
    the current engine time

Fixes flutter/flutter#40281

Let's stop using auto here since the right hand size is no longer consistent; I don't actually know offhand which way the conversion will go, so I no longer know the exact type. We should explicitly use nanoseconds.
