Pull request overview
This PR resolves file locking issues with MSBuild tasks by adopting TaskHostFactory and simplifies the tasks build process by removing .NET Framework support and custom incremental build logic.
- Removes complex incremental build logic that used synthetic inputs/outputs to avoid file locks
- Standardizes all MSBuild task invocations to use TaskHostFactory with Runtime="NET"
- Simplifies task projects to only target .NET Core (removing .NET Framework multi-targeting)
- Removes the RegenerateDownloadTable task and associated infrastructure which was no longer needed
