Angular error handler should report `handled: false`

[bruno-garcia]

Currently the Angular error handler integration executes a normal captureException:

sentry-javascript/packages/angular/src/errorhandler.ts

Line 43 in 925c114

const eventId = runOutsideAngular(() => Sentry.captureException(extractedError));

This results in a handled error in Sentry:

Mechanism ideally would be angular or something that helps differentiate where it comes from.
Example event in sentry

@vladanpaunovic @smeubank there's a PR open for a year that addresses this (#3844), can we get it merged please? 🙏

I see prio is low. To be fair this affects Release Health, prioritization (since unhandled errors have higher priority) and the label on the produdct. I'd argue this is high priority as it's Sentry's main product: error reporting

Thanks @bruno-garcia, @onurtemizkan rebased the PR and @Lms24 will review it. Looking forward to bring this in soon.
