Global handler for catching any unhandled rejection

[darky]

Would be good to have ability to setup global handler for catching any unhandled rejection Something like process.on('unhandledRejection', ... in Node.js https://nodejs.org/dist/latest-v18.x/docs/api/process.html#event-unhandledrejection

The main issue I found for it, is that we need to dectect JVM, JS/Browser, JS/Node. If you think you can implement and uniform api that works for all the cases, the PR will be welcome.

Probably promesa.util is good namespace to place this code.
