Making setOutput in SentrySDKLog.swift public to make it possible to forward logs to the JS console

[alwx]

📜 Description

This PR adds one tiny change to the codebase — it makes setOutput in SentrySDKLog.swift public.
That's required by RN SDK (and probably other hybrid SDKs as well) in order to support log forwarding — the ability to see native logs in JS console: getsentry/sentry-react-native#5622

(there are also some formatting changes done here but they were done automatically after I ran make format)

📝 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.
