NuGetizer is incompatible with SDK Pack DevelopmentDependency property

[kzu]

Describe the Bug

If you set $(DevelopmentDependency)=true in the csproj, nugetizer does not emit the right developmentDependency metadata.

We instead have our own IsDevelopmentDependency. We should deprecate that in favor of the SDK one.

See https://github.com/NuGet/Home/wiki/DevelopmentDependency-support-for-PackageReference for more information.
