core: crypto add support for SM2 DSA
Adds SM2 Digital Signature Algorithm [1] using LibTomCrypt. The TA
interface complies with the GlobalPlatform TEE Internal Core API
version 1.2.
SM2 DSA is enabled with CFG_CRYPTO_SM2_DSA=y (default y) which currently
requires that CFG_CRYPTOLIB_NAME=tomcrypt. An Mbed TLS implementation
could be added later if needed.
