Update licensing metadata (#2593)

The PR changes the license from `BSD-2-Clause` to `BSD-3-Clause`, so
called the “New BSD License” or “Modified BSD License”.
Also that aligns the license used by MKL components or by NumPy.

The license header is updated with `BSD-3-Clause` per each impacted file
in the repository.
