Code Quality: Introduce Directory.Packages.props for better dependency management

[Lamparter]

Description

Similar to #14826, which would allow for seamless property management across projects, but instead this would allow for seamless package management. This would allow for easier ability to update dependencies across projects.

Concerned code

All projects.

Gains

• Better ability to update dependencies
• Easier way to see all the dependencies used by the projects and quickly identify each of them
• Offers similar benefits to using Directory.Build.props

Requirements

Very easy:

• Create Directory.Packages.props file
• Migrate package references into the file
• Remove version references from project files
• Add package references to project files
