ODL is being packaged with the wrong framework

[robertmclaws]

The new .NET 8 assemblies are still being packages with .nuspec files instead of letting SDK-style project files do the work. Those .nuspac files have not been updated, so natively-compiled .NET 8 assemblies are being incorrectly delivered into .netstandard2.0 folders in the NuGet package.

Assemblies affected

ODL 8.x

Reproduce steps

• Open the Microsoft.Data.Edm.csproj file and see that it targets .NET 8.0 exclusively.
• Open the NuSpec file and see that the .NET 8 assembly is incorrectly packaged into the .NET Standard 2.0 folder.

Expected result

The SDK-style projects would manage the different <TargetFrameworks> supported and add their compiled assets to the NuGet package appropriately.

Actual result

Features that are not supported by .NET Standard 2.0 are being compiled into incorrectly-constructed NuGet packages that may be causing issues downstream.
