aes-cmac: aes-cmac function using cryptolib.

[KianBahasadri]

Hello, I've added a simple function that performs AES CMAC using the builtin cryptolib library. The code is from my own repository micropython-aes-cmac.

I did my best to meet the code and commit conventions, I used black to format my code, I also signed off my commit and followed the specified format.

Please let me know what improvements I could make. Thanks.
