Structured Logs: Add log APIs to Hub and Client

[denrase]

📜 Description

• Adds capture(log:scope:) methods to Client
• Adds logger API to Hub
• Moves attributes enrichment of logs into batcher, so that hub/scope calls also get them.
• Provides additional workarounds for circular issues regarding Logs an ObjC/Swift
• Adds public initializers to SentryLog, so users can actually create them for hub/client method usage.

💡 Motivation and Context

Closes #6503

💚 How did you test it?

Unit tests

📝 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.

@philipphofmann Hacked this together. Works locally. If there are no other blockers, everything should work out without breaking existing public API.
