Merged PR 49951: [AI Evaluation] Cherry pick commits for 9.5 preview release

#### AI description  (iteration 1)
#### PR Classification
This PR cherry picks commits for the 9.5 preview release and introduces API improvements, interface renaming, and caching logic updates.

#### PR Summary
The PR streamlines caching in AI Evaluation by removing legacy CacheOptions and updating related interfaces while also enhancing JSON converters and chat extension methods. Key changes include:
- **`src/Libraries/Microsoft.Extensions.AI.Evaluation.Reporting/CSharp/Storage/DiskBasedResponseCache.cs`**: Removed CacheOptions logic, added a configurable TTL parameter, and refactored cache methods.
- **Interface Renaming**: Renamed `IResponseCacheProvider` to `IEvaluationResponseCacheProvider` and `IResultStore` to `IEvaluationResultStore` across core code and associated tests.
- **`src/Libraries/Microsoft.Extensions.AI.Evaluation.Reporting/CSharp/ChatDetailsExtensions.cs`**: Modified the `AddTurnDetails` extension to accept multiple chat turns.
- **JSON Serialization**: Updated converters in `AzureStorageJsonUtilities.cs` and `JsonUtilities.cs` to use newer types (e.g., `CamelCaseEnumConverter`, `TimeSpanConverter`, and added `EvaluationContextConverter`).
- **`src/Libraries/Microsoft.Extensions.AI.Evaluation/EvaluationRating.cs`**: Reordered and renamed enum values to better reflect the intended rating semantics.
