core: crypto: add support for SM2 KEP

Adds SM2 Key Exchange Protocol [1] using LibTomCrypt. The TA interface
complies with the GlobalPlatform TEE Internal Core API version 1.2.

SM2 KEP is enabled with CFG_CRYPTO_SM2_KEP=y (default y) wich currently
requires that CFG_CRYPTOLIB_NAME=tomcrypt. An Mbed TLS implementation
could be added later if needed.
