feat(core): [Global Attributes 1] Add scope-level attributes API

[adinauer]

📜 Description

Add a new API to set attributes on scopes (IScope, IScopes, Sentry). Attributes are key-value pairs (SentryAttribute) that can be set, removed, and queried from scopes. The CombinedScopeView merges attributes across scope layers (global, isolation, current) with the current scope taking precedence.

This lays the foundation for scope-level attributes that can be automatically attached to logs, metrics, and other events.

💡 Motivation and Context

Scope-level attributes allow users to set contextual key-value pairs that are automatically propagated to logs and metrics, similar to how tags work but using the structured SentryAttribute type. A follow-up stacked PR will wire these attributes into LoggerApi and MetricsApi.

💚 How did you test it?

• Unit tests for Scope attribute operations (set, remove, getAttributes, setAttributes)
• Unit tests for CombinedScopeView attribute merging across scope layers

📝 Checklist

• I added GH Issue ID & Linear ID
• 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.

🔮 Next steps

• Stacked PR to wire scope attributes into LoggerApi and MetricsApi, including extracted factory methods (SentryAttributeType.inferFrom, SentryLogEventAttributeValue.fromAttribute)
