Adds fault mitigation in mbedtls_rsa_rsassa_pkcs1_v15_verify() by using
the macro FTMN_CALLEE_DONE_MEMCMP() instead of just
mbedtls_safer_memcmp() when checking that the hash in the RSA signature
is matching the expected value.
FTMN_CALLEE_DONE_MEMCMP() saves on success the result in a thread local
storage if fault mitigations was enabled when the function was called.
