fix: Potential app launch hang caused by the SDK

[philipphofmann]

📜 Description

Remove unused crash report fields binary_cpu_type and binary_cpu_subtype so we can also remove the call to _dyld_get_image_header, which lead to app launch hangs for a customer. Still, these
fields might be useful and we can readd them with GH-6180.

💡 Motivation and Context

Quick fix for #6180

💚 How did you test it?

1. Unit tests are still green. We have plenty of crash reports in our tests that have the binary_cpu_subtype and binary_cpu_type, so we test that if previous reports contain this info, we handle it correctly.
2. Manually crashing with a simulator from main and then relaunching an app with a simulator on this branch: https://sentry-sdks.sentry.io/issues/6774282031/events/1e11ac3ac75d44f89c49838f5ad1f7af/?project=5428557
3. Manually crashing and relaunching an app with a simulator, all on this branch: https://sentry-sdks.sentry.io/issues/6774282031/events/69ca9b30a0ea4252885f62ce80a6090c/?project=5428557

📝 Checklist

You have to check all boxes before merging:

• I added tests to verify the changes.
• No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled.
• I updated the docs if needed.
• I updated the wizard if needed.
