crypto: x86/sm4 - export reusable AESNI/AVX functions
Export the reusable functions in the SM4 AESNI/AVX implementation,
mainly public functions, which are used to develop the SM4 AESNI/AVX2
implementation, and eliminate unnecessary duplication of code.
At the same time, in order to make the public function universal,
minor fixes was added.
