Pull Request Overview

This PR migrates the Azure Functions Host repository to use central package management via Directory.Packages.props files. The migration simplifies package version management by centralizing version definitions and leveraging MSBuild's central package management features.

Key Changes:

• Introduces central package management with Directory.Packages.props files at repository and project levels
• Removes explicit version numbers from individual project files, relying on centralized version definitions
• Standardizes StyleCop package usage across the solution while temporarily removing it from projects with warnings
• Updates MSBuild imports to use GetPathOfFileAbove for improved path resolution
