chore: Logic for full blocking app hangs

[philipphofmann]

📜 Description

Change the logic for detecting app hangs in the ANRTrackerV2 to use frames delay to detect app hangs. The first step is to only report a fully blocking app hang if the app didn't render a single frame in the timeoutInterval of the ANRTrackerV2.

It's worth noting that the SentryANRTrackingIntegrationV2 doesn't exist in the options yet, and further
work is required to surface this new feature to our users. Still, we should give this a thorough review. The diff looks huge, but it's mostly tests.

This PR is based on #4279.

#skip-changelog

💡 Motivation and Context

This is required for #3492.

💚 How did you test it?

Unit tests and on a real device.

Sorry, the stacked PRs messed up the diff. I need to merge main back into here. Then it should be ready for review.

[brustolin]

The new algorithm looks good to me.

P.S.: Anything that prevents us from written the V2 in swift already?
