Introduce a new msbuild property to exclude build output for specific tfms during pack task

[Anipik]

Nuget currently provides a msbuild called IncludeBuildOutput to disable including the build output for all tfms.
Nuget provides this kind of feature for other targets like _GetFrameworksWithSuppressedDependencies which run during the pack command.
It will enable the scenario where developer wants to exclude a certain kind of build output for a specific tfm.

Or just respect the existing property in inner builds as well?

yep i thought that as well, just added a new one to just start the discussion. moving the existing property to innerbuilds will be optimal

[ViktorHofer]

Agreed, this is a good way to start a discussion. What confused me is that you already opened a PR with a new property name. The problem with a new property is that even if it will be documented (which it should be), it would cause confusion about the differences between the existing and the new one.

[nkolev92]

I think reusing the existing property is better than the new one.
Thinking through it, I don't think there should be any concerns with compat with that either.

@Anipik
This PR introduced regression bug issue#10462. So we're reverting the merge.
Can you check what was the problem and rectify it and create new merge PR request?
