This check-in supports Romain Geissler's work on cleaning up our use of ::byte when it collides with std::byte. Regardless of what happens, such as removing ::byte and adding CryptoPP::byte, providing the typedef here makes Kalyna immune to the outside changes. Also see Pull Request 437 and 438.
The code at check-in a5c67cfdd6 did not include it. Unlike Threefish, it looks like Kalyna could benefit from the cache hardening given how similar Kalyna is to AES. The hardening costs less than 0.1 cpb, which equates to about 199 MB/s vs 201 MB/s on a 6th gen Skylake
