Pull Request Overview

This PR replaces the old Build.csproj approach with MSBuild props and targets, refactors repo structure, and updates CI pipelines to run tests and RID builds in parallel.

• Introduce Directory.Build.props/targets and related MSBuild files under eng/build/
• Add a standalone GoZipTool project and integrate its build into the CLI MSBuild
• Revamp CI YAML: use $(SrcRoot)/$(EngBuildRoot) paths, parallelize builds/tests, and update artifact signing

• The Dockerfile no longer copies and runs download-templates.ps1, which may prevent the templates.json from being generated in the container. Ensure MSBuild's DownloadAndExtractTemplatesJson target runs successfully in this image or reintroduce the script step.
