core: crypto: add support for SM2 PKE
Adds SM2 Public Key Encryption [1] using LibTomCrypt. The TA interface
complies with the GlobalPlatform TEE Internal Core API version 1.2.
SM2 is enabled with CFG_CRYPTO_SM2_PKE=y (default y) which currently
requires that CFG_CRYPTOLIB_NAME=tomcrypt. An Mbed TLS implementation
could be added later if needed.
