✨ [RUM-4013] DD_RUM: add handling stack in beforeSend context

[thomas-lebeau]

Motivation

Create a stack trace and expose it in the beforeSend's domainContext argument.
It allow customers to initialise the browser SDK with something like:

const SERVICE_REGEX = /(?:browser-sdk-test-playground\/module-federation\/|webpack:\/\/)(?<service>\w*)\//;
  
DD_RUM.init({
  beforeSend: (event, context) => {
    const service =
      context?.handlingStack?.match(SERVICE_REGEX)?.groups?.service;

    if (service) {
      event.service = service; //TODO: this is not yet implemented
    }
    return true;
  },
});

Changes

support the following APIs

• DD_RUM.addError()
• DD_RUM.addAction()
• fetch() resources
• xhr resources
• console errors

Testing

• Local
• Staging
• Unit
• End to end
