Pull request overview

This PR refactors the repo’s release-preparation tooling so it can be packaged and reused across repositories, while expanding processing to include both shipping and non-shipping drop assets and adding pipeline-driven filtering (e.g., skipping specific files during release preparation).

Changes:

• Package DiagnosticsReleaseTool as a .NET tool (Microsoft.Diagnostics.ReleaseTool) and wire it into the repo build.
• Extend drop acquisition and release processing to include non-shipping assets, and propagate a “public vs internal-only” designation via IsAssetForPublicRelease.
• Move repo-specific constants into tool-list.json and add skip-file support (used to skip MergedManifest.xml in pipelines).
