The structures related to CMAC, GCM, CCM and
CHACHAPOLY operations are defined in
crypto_builtin_composites.h not in
crypto_struct.h. Thus move the cmac.h, gcm.h,
ccm.h and chachapoly.h header inclusions from
crypto_struct.h to crypto_builtin_composites.h.

- Add `alg` and `computation_stage` to `psa_pake_operation_s`.
Now when logic is moved to core information about `alg` is required.
`computation_stage` is a structure that provides a union of computation stages for pake algorithms.
- Move the jpake operation logic from driver to core. This requires changing driver entry points for `psa_pake_output`/`psa_pake_input` functions and adding a `computation_stage` parameter. I'm not sure if this solution is correct. Now the driver can check the current computation stage and perform some action. For jpake drivers `step` parameter is now not used, but I think it needs to stay as it might be needed for other pake algorithms.
- Removed test that seems to be redundant as we can't be sure that operation is aborted after failure.

For sign and verify, the pointer passed in to the hash is not guaranteed to
remain valid inbetween calls, thus we need to store the hash in the
operation. Added a test to ensure this is the case.

Also make previous changes apply to both interruptible sign hash operation
structures rather than just the one as it was.

This commit removes the test_psa_crypto_config_basic
all.sh component that can no longer work without
adapting it to the separately compiled test driver
library. This component is replaced by several
components in the following commits to test various
type of acceleration independently.

Also fiixed the following merge problems:
crypto_struct.h : Added MBEDTLS_PRIVATE to psa_aead_operation_s
members (merge conflict)
psa_crypto_aead.c : Added ciphertext_length to mbedtls_gcm_finish
call (change of API during development)

It makes sense to do the length checking in the core rather than expect
each driver to deal with it themselves. This puts the onus on the core to
dictate which algorithm/key combinations are valid before calling a driver.
Additionally, this commit also updates the psa_mac_sign_finish function
to better deal with output buffer sanitation, as per the review comments
on #4247.

Prefix with 'mbedtls_psa' as per the other types which implement some
sort of algorithm in software.

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.

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.

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.

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.
