Introduce activity execution record capturing and serialization improvements

[sfmskywalker]

• Added middleware for capturing activity execution records during workflow execution.
• Introduced async mapping in DefaultActivityExecutionMapper with additional serialization support.
• Enhanced ActivityExecutionRecord with new serialized properties for efficient storage.
• Updated extensions to include UseActivityExecutionLogCapturing.
• Simplified logging persistence by leveraging pre-serialized values in ActivityExecutionLogStore.

Fixes #6799

Pull Request Overview

This PR introduces activity execution record capturing and serialization improvements to enhance workflow execution logging. The changes optimize performance by pre-serializing activity execution data during middleware execution rather than at persistence time.

• Added middleware-based activity execution record capturing with async mapping support
• Enhanced serialization handling by moving compression and serialization from persistence layer to mapping layer
• Simplified persistence operations by leveraging pre-serialized data in the store
