Add a CMAC test We did not have a test of the low level CMAC APIs so we add one. This is heavily based on the HMAC test. Reviewed-by: Richard Levitte <levitte@openssl.org> (Merged from https://github.com/openssl/openssl/pull/11972)

/*
Update CMAC cipher algorithm list and test cases. 1. Update manual, add SM4-CBC to CMAC cipher algorithm list. 2. Add test case for SM4-CBC CMAC, add "data length is greater than 4 block-length" cases for aes-128-cbc, aes-192-cbc, aes-256-cbc and des-ede3-cbc.

Update CMAC cipher algorithm list and test cases. 1. Update manual, add SM4-CBC to CMAC cipher algorithm list. 2. Add test case for SM4-CBC CMAC, add "data length is greater than 4 block-length" cases for aes-128-cbc, aes-192-cbc, aes-256-cbc and des-ede3-cbc.
