Append missing context from Native SDK for iOS

[marandaneto]

Similar to https://github.com/getsentry/sentry-dart/pull/761/files

Missing tags, extra, user, dist, environment, fingerprint, level, breadcrumbs...
Ideally, every scope data set in the Native SDK makes it to the Events captured by JS as well.

This issue has gone three weeks without activity. In another week, I will close it.

But! If you comment or otherwise update it, I will reset the clock, and if you label it Status: Backlog or Status: In Progress, I will leave it alone ... forever!

Right RN -> iOS only merges the contexts and user, https://github.com/getsentry/sentry-react-native/blob/main/src/js/integrations/devicecontext.ts
But it should merge/fill the missing objects as well the tags, extra, dist, environment, fingerprint, level, breadcrumbs.

This might be a breaking change due to the inclusion of the event.fingerprint.

That's fine, its part of the v5 milestone anyway.
