lib/crypto: sha2: Add hmac_sha*_init_usingrawkey()
While the HMAC library functions support both incremental and one-shot
computation and both prepared and raw keys, the combination of raw key
+ incremental was missing. It turns out that several potential users of
the HMAC library functions (tpm2-sessions.c, smb2transport.c,
trusted_tpm1.c) want exactly that.
Therefore, add the missing functions hmac_sha*_init_usingrawkey().
Implement them in an optimized way that directly initializes the HMAC
context without a separate key preparation step.
Reimplement the one-shot raw key functions hmac_sha*_usingrawkey() on
top of the new functions, which makes them a bit more efficient.
