lib/crypto: sha256: Add HMAC-SHA224 and HMAC-SHA256 support
Since HMAC support is commonly needed and is fairly simple, include it
as a first-class citizen of the SHA-256 library.
The API supports both incremental and one-shot computation, and either
preparing the key ahead of time or just using a raw key. The
implementation is much more streamlined than crypto/hmac.c.
I've kept it consistent with the HMAC-SHA384 and HMAC-SHA512 code as
much as possible.
Testing of these functions will be via sha224_kunit and sha256_kunit,
added by a later commit.
