Link AppHangs to Profiles

[philipphofmann]

Description

We plan to implement continuous profiling somewhere in 2024 or maybe later (https://github.com/getsentry/sentry-cocoa/issues/3555). Once we achieved that, we could link our app hang events to profiles so users get more context around what caused an app hang. This would be especially useful for app hangs that don't fully block the main thread, for which our SDK can't get reliable stack traces, see https://github.com/getsentry/sentry-cocoa/issues/3492. To make this a valuable feature we also need changes in Sentry to properly display the link between app hangs and the profile. Please upvote if you want this feature.
