N-API: add function for fatal error

Expose node::FatalError() (or similar) as a napi_fatal_error() API.

See nodejs/node-addon-api#32 (comment) for a scenario where it is needed.

The N-API team will get to this based on priorities, but this is a good place for others to contribute as well. If you start working on this, assign the issue to yourself and add a comment that you are working on it.

I'm planning to take a look at it this week.
