lib/crypto: sha2: Provide functions for zeroizing SHA2 hmac_sha* structures
In certain cases crypto code functions need to zeroize their local SHA2
hmac_sha*_key or hmac_sha*_ctx structures after use to avoid leaking
sensitive material on the stack.
Provide hmac_sha*_zeroize_key() and hmac_sha*_zeroize_ctx() helper
functions that can be used with __cleanup() to automatically zeroize
the structure when it goes out of scope.
