4f7cae6cbe Rename HMAC operation structure
Prefix with 'mbedtls_psa' as per the other types which implement some
sort of algorithm in software.

b4b9b2879c Remove redundant key_set from MAC operation structure
The purpose of key_set was to guard the operation structure from being
used for update/finish before a key was set. Now that the implementation
fully adheres to the PSA API, that function is covered by the `alg`
variable instead. It's set to the algorithm in use when a key is set, and
is zero when the operation is reset/invalid.

5c85ef0a56 Remove unused items from MAC operation context structure
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.

f64b25e205 Rename internal HMAC structure type to match convention
Typedef'ed structures are suffixed _t
Also updated the initialiser macro with content that actually
matches the structure's content.

76720f6389 Complete, document and fully use internal HMAC API
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.

aecf0d3e70 Add include headers for composite operation contexts and move hmac
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.
