libmbedtls: add interfaces in mbedtls for context memory operation

For integrating into OPTEE_OS, it needs add some interfaces:
1. add mbedtls_cipher_clone() for cipher to copy context between two
operations.
2. add mbedtls_cipher_setup_info() for cipher. cipher need to get its
"cipher_info" according the key length, while the key length is not an
input in allocate function. So, use a default key len in the beginning.
It need to reset the cipher info again in init function.
3. add mbedtls_cipher_cmac_setup() for cmac. This function is separate
from mbedtls_cipher_cmac_starts().
4. copy hmac context in md.
