feat (android): global UnhandledRejection redirector to JSDialogError and uncaughtException handler

[Informate]

GitHub Issues: #14177

Optional Description:

The unhandledRejection V8 event is unhandled by Titanium SDK at the moment, and the unhandledRejections event get silently lost.

This commit fixes the issue handling the V8 event and sending it from V8Runtime to the JS environment thorw Kroll with just few changes and modify.

The JS Error Dialog shows correctly and the Rejected Promises can now be cacthed by uncaughtException as an exception with type='Rejected Promise' (still not a Ti.App unhandledRejection event).

Code Example:

Ti.App.addEventListener('uncaughtException',(err)=>console.error(err));
(async ()=>{
  throw new Error("Show me this ERROR !!!!");
})();

Please add the code example to the first post (edit it) so people know how to test it.
