[TheAngryByrd]

closes #236, though we need a separate issue to try to contribute this upstream to the SDK.

• Extend ProjectInfo types to include Analyzers, AllProperties, and AllItems.
• Implement logic to collect all properties and items during project evaluation.
• Add a test case for loading a project with NuGet analyzers.
• Create sample project files for testing F# analyzers.
