Apple: Remove Cocoa SDK Frames for Generating Stacktraces

### Environment

SaaS (https://sentry.io/)

### Version

_No response_

### Steps to Reproduce

- View a crash report for a report submitted by `SentrySDK.captureError()` (Sentry Cocoa 7.5.2)
- Make sure it's showing "App Only" view.

### Expected Result

I expected it to only show stack traces for my app.

### Actual Result

The first stack trace is:

> -[SentryStacktraceBuilder buildStacktraceForCurrentThread]

While I understand it sometimes can be useful to see where it crashed in a system framework. Seeing internal Sentry stack traces is not useful.
