Apparently it was at some point assumed that there would be
support for MAC algorithms with IV, but that hasn't been
implemented yet. Until that time, these context structure
members are superfluous and can be removed.

Typedef'ed structures are suffixed _t
Also updated the initialiser macro with content that actually
matches the structure's content.

Since HMAC moved into its own compilation unit, the internal API needed
to be documented and finalized. This means no more reaching deep into
the operation structure from within the PSA Crypto core. This will make
future refactoring work easier, since internal HMAC is now opaque to the
core.

Step 3/x in moving the driver. Separate commits should make for easier
review.
Additional changes on top of code movement:
* Copied the implementation of safer_memcmp from psa_crypto into
psa_cipher_mac since the mac_verify driver implementation
depends on it, and it isn't available through external linkage

Step 2/x in moving the driver. Separate commits should make for easier
review.
Additional changes on top of code movement:
* Early-return success on input with zero-length to mac_update, to
avoid NULL pointers getting passed into the driver dispatch

Step 1/x in moving the driver. Separate commits should make for easier
review.
Additional changes on top of just moving code:
* Added a sanity check on the key buffer size for CMAC.
* Transfered responsibility for resetting the core members of the
PSA MAC operation structure back to the core (from the driver
wrapper layer)

This is a temporary measure. Other operations in the PSA Core which rely
on this internal HMAC API should be rewritten to use the MAC API instead,
since they can then leverage accelerated HMAC should a platform provide
such acceleration support.

Modeled after the include chain of the primitive operation contexts.
Also moved the HMAC context structure to the builtin composites file,
since that is where it conceptually belongs. This is a preparatory
step for implementing driver dispatch of MAC multipart operations.

This was probably included by mistake, because the file itself is part
of the inclusion chain starting with crypto.h.
Signed-off-by: Steven Cooreman <steven.cooreman@silabs.com>
This is a preparatory step in order to be able to organize the include
chain from crypto_struct in such a way that the MAC operation structure
for the PSA 'software' driver can make use of the hash operation structure.
Conceptually:
* Primitives:
* Hash
* Cipher
* Composites:
* AEAD (can use cipher)
* MAC (can use cipher and/or hash)

Zephyr's native posix port define _POSIX_C_SOURCE with a higher value
during the build, so when mbedTLS defines it with a different value
breaks the build.
As Zephyr is already defining a higher value is guaranteed that mbedTLS
required features will be available. So, just define it in case it was
not defined before.

For now the entries are in no particular order. Before the release we
should have a final pass over this document and order them from most
impactful to least impactful. We might even create sections, a table of
contents, etc.
In the meantime, each PR should add an entry about it changes.
