feat(core): [Global Attributes 5] Support collections and arrays in log attributes

[adinauer]

📜 Description

Adds ARRAY type support for log attribute type inference. Collections (List, Set, etc.) and arrays passed as attribute values are now correctly typed as "array" instead of falling through to "string" via toString().

Changes:

• Add ARRAY enum value to SentryAttributeType
• Update inferFrom() to detect Collection and array types
• Add arrayAttribute() factory method to SentryAttribute
• Add serialization test fixtures for array attributes

This follows the Python SDK's approach of using "array" as the attribute type for homogeneous collections.

💡 Motivation and Context

Fixes #5074 — Collections passed as log attribute values were being converted to strings, losing their structure. The serialization layer (JsonObjectSerializer) already handles Collections and arrays as JSON arrays, so only the type enum and inference needed updating.

💚 How did you test it?

• Added 7 unit tests in SentryAttributeTypeTest covering List<String>, List<Integer>, Set<Boolean>, String[], int[], empty list, and mixed-type list
• Updated SentryLogsSerializationTest with array attribute round-trip (serialize + deserialize)

📝 Checklist

• I added tests to verify the changes.
• No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled.
• No breaking change or entry added to the changelog.
• No breaking change for hybrid SDKs or communicated to hybrid SDKs.

🔮 Next steps

Stacked on #5075 (fix/attribute-integer-type-detection).

New arrayAttribute factory method is entirely unused and untested

Low Severity

The new arrayAttribute() factory method is never called anywhere in the codebase — not in production code and not in any tests. Every other sibling factory method (booleanAttribute, integerAttribute, doubleAttribute, stringAttribute) has test coverage and production usage, but arrayAttribute has none. This also means the method's behavior (e.g., correctly setting SentryAttributeType.ARRAY) is unverified.
