Reuse util classes for System tests

[adinauer]

#skip-changelog

📜 Description

Classes that were duplicated across all system test modules are now located in the sentry-system-test-support module.

💡 Motivation and Context

Allows us to have less duplication, making it easier to add new tests.

💚 How did you test it?

📝 Checklist

• 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.
• Review from the native team if needed.
• No breaking change or entry added to the changelog.
• No breaking change for hybrid SDKs or communicated to hybrid SDKs.
