VS: Support C# project references

When specifying a pure C# target in the `target_link_libraries()` call to
another C++ target, a `<ProjectReference>` was setup for it (we wanted this)
but also a corresponding `.lib` was added under `<AdditionalDependencies>`
(we didn't want this).

This change introduces a check that prevents `.lib` linker options from
being used when the corresponding target for that library is a C# target.

Fixes: #17678
