Motivation and Context

Not all windows builds use the MSVC generator, for example the CLion can be used as an IDE and dispatch to the MSVC compiler. MSVC creates different names for some libraries eg. libpng-d.lib. This does not happen with the Ninja generator, so these debug libraries cannot be found when using a different generator.

Checklist:

• I have run python util/check_style.py --apply to apply Open3D code style
  to my code.
• This PR changes Open3D behavior or adds new functionality.
  • Both C++ (Doxygen) and Python (Sphinx / Google style) documentation is
    updated accordingly.
  • I have added or updated C++ and / or Python unit tests OR included test
    results (e.g. screenshots or numbers) here.
• I will follow up and update the code if CI fails.
• For fork PRs, I have selected Allow edits from maintainers.

Description

This PR has cmake check the generator instead of the compiler to determine if these different names should be added. Also updated the tbb target name that is copied for the test.exe target to its namespaced version TBB::tbb.

I don't think these changes are worth updating the changelog, but I'm open to other opinions.

Hmmm, the rabbit hole goes deeper than I expected. This is not ready to merge yet.
