Pull request overview

This PR adds WinML 2.0 “preview” verification samples across multiple SDKs and updates the SDKs/pipelines to support execution-provider (EP) discovery + download/registration flows and WinML-targeting changes.

Changes:

• Add new “verify-winml” samples for C++, C#, Python, JavaScript, and Rust, plus update existing audio transcription samples to align with newer streaming/download APIs.
• Extend the C++ SDK manager to support EP discovery and EP download/registration with optional progress reporting, and invalidate the catalog cache after EP changes.
• Update WinML target framework/min-version pins across .NET projects and pipeline build steps; adjust JS WinML installer robustness and fix C# catalog ordering behavior.
