Remove NetCoreReference

This removes the `NetCoreReference` infrastructure and replaces it with `DefaultReferenceExclusion` to remove the one problematic implicit reference to WindowsBase. Manually picking references was blocking using System.Private.Windows.Core from the WinForms repo. Not having this also greatly simplifies the projects. This also tweaks the solution to add folders docs and eng items. Fixes dotnet#9168

 In addition to these, care must be taken for the following: 
 
 - Use `<EmbeddedResource>` instead of `<Resource>`

-- Always use `<NetCoreReference>` instead of implicitly acquiring the full set of `Microsoft.NetCore.App` references. 
-  - `Microsoft.NetCore.App` contains a version `WindowsBase` that clashes with WPF's `WindowsBase` during markup compilation.
-  - To avoid this clash, we must always specify the references we need explicitly. 
-  - Also, our code-base requires that all references be specified explicitly anyway to avoid inadvertent reference-creep to bug-fixes.
