Type de-duplication from openai-java for azure-ai-agents and azure-ai-projects packages

[jpalvarezl]

This pull request refactors the Azure AI Agents SDK to support direct interoperability with openai-java models for filter and reasoning types, reducing duplication and simplifying serialization logic. The most important changes are the removal of Azure-specific filter and reasoning model classes, addition of new serialization helpers, and updates to agent and tool classes to accept openai-java types.

Removal of Azure-specific filter and reasoning model classes

• Deleted ComparisonFilter, ComparisonFilterType, CompoundFilter, and CompoundFilterType classes from com.azure.ai.agents.models, removing Azure-specific filter type definitions in favor of openai-java types. [1] [2] [3] [4]

Serialization and interoperability enhancements

• Added toBinaryData and fromBinaryData methods to OpenAIJsonHelper for converting openai-java objects to and from BinaryData, enabling seamless serialization/deserialization between Azure and openai-java models.
• Updated imports in relevant files to use OpenAIJsonHelper for serialization tasks. [1] [2]

Updates to agent and tool classes for openai-java compatibility

• Modified PromptAgentDefinition to use com.openai.models.Reasoning directly for its reasoning property, updating its getter, setter, serialization, and deserialization logic accordingly. [1] [2] [3] [4] [5] [6]
• Added overloads to FileSearchTool allowing filters to be set using openai-java ComparisonFilter or CompoundFilter types, with conversion handled by OpenAIJsonHelper.

These changes streamline the SDK's support for openai-java models, making it easier to integrate and reducing code duplication.

Pull request overview

This PR refactors azure-ai-agents to interoperate directly with openai-java reasoning and filter model types, reducing duplicated Azure-side model classes and centralizing JSON interop via helper utilities.

Changes:

• Replaced Azure-specific Reasoning/filter model types with com.openai.models.* equivalents and updated serialization/deserialization paths.
• Added OpenAIJsonHelper utilities to convert openai-java model instances to/from BinaryData.
• Added/updated unit tests covering reasoning and file-search filter round-trips.
