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. Signed-off-by: Steven Cooreman <steven.cooreman@silabs.com>

* Context structure declaration of the Mbed TLS software-based PSA drivers

|
|
* This file contains the context structures of those algorithms which need to
|
|
* rely on other algorithms, i.e. are 'composite' algorithms.

|
|
* \note This file may not be included directly. Applications must

*
|
|
* \note This header and its content is not part of the Mbed TLS API and
|
|
* applications must not depend on it. Its main purpose is to define the
|
|
* multi-part state objects of the Mbed TLS software-based PSA drivers. The
|
|
* definition of these objects are then used by crypto_struct.h to define the
|
|
* implementation-defined types of PSA multi-part state objects.
