Log Integrations: Add SentryCocoaLumberjack integration

[denrase]

#skip-changelog

📜 Description

• Adds the SentryCocoaLumberjack integration to the 3rd-party-integrations/SentryCocoaLumberjack folder
• Skipping changelog as this is not available to users through this repo

💡 Motivation and Context

Closes #6278
Relates to #6902

💚 How did you test it?

• Runs pure swift tests against the current Package.swift version
• This loads pre-build artefacts, so we always test against already released versions.

📝 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.
• 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.
