Replace spelled out logical operators: breaks Kokkos windows tests

Let's avoid forcing default behavior change on downstream users.

I was going to say that including <iso646.h> is the suggested option.

The alternative spellings are required by the C++ Standard. Windows is nonconforming because it requires use of a header. That being said, I don't object to the proposed solution.

Including that thing is transitive though, do we really want to change the default behavior of MSVC for everyone downstream?

Just FYI, including that header doesn't "change the default behavior of MSVC," it makes MSVC conform to the C++ Standard a bit better. That being said, I don't object to the proposed solution.
