TfmSpecificDebugSymbolsFile is not used when IncludeBuildOutput is set to false

[AndriySvyryd]

Describe the bug

We set TfmSpecificDebugSymbolsFile to add additional PDBs for the symbols package and we have to set IncludeBuildOutput to be able to change the target path of the artifacts, but with this combination PDBs are not included in the symbols package.

To Reproduce

See dotnet/efcore#37865 (comment)

We hit this also. For this and few other issues that pack no longer works, we maintain an internal patched targets and SDKs that we use it on CI and on local builds. It's becoming harder and harder to maintain.

I hope NuGet Pack gets much needed fixes and features from v10.0+ .NET SDKs onwards. It's been neglected too much.
