Move the docuumentation files that after
the split will fit better in TF-PSA-Crypto
than Mbed TLS. No comment update.

This reverts commit 939ce9d0d543530b84eef05405ee21ee89eb8246.
Build mbedtls_test library of objects to link
with TLS and x509 test suites and programs
with mbedtls framework not TF-PSA-Crypto
one (when it will be there).

Move test_keys.h to tests/include/test
instead of tests/src as it is used
outside of tests/src namely by
test_suite_pk.

For ECDSA verification, there is no difference between the deterministic and
randomized algorithm. The PSA core consider the two variants as identical as
far as key policies are concerned, and the built-in implementation accepts
either variant even if only the other variant is supported for signature.
In p256-m, accept to perform an ECDSA verification when the algorithm is
specified as deterministic ECDSA. This makes the behavior identical to the
built-in implementation, which is less surprising for users and saves us
from having to cope with a difference in our testing.

In particular, if interruptible ECDSA is supported but not the deterministic
variant, detect this in psa_sign_hash_start(), whereas before start() would
succeed and psa_sign_hash_complete() would fail. This avoids an
inconsistency between psa_sign_hash() and psa_sign_hash_start() that would
be annoying to handle in test_suite_psa_crypto_op_fail.

ECDSA has two variants: deterministic (PSA_ALG_DETERMINISTIC_ECDSA) and
randomized (PSA_ALG_ECDSA). The two variants are different for signature but
identical for verification. Mbed TLS accepts either variant as the algorithm
parameter for verification even when only the other variant is supported,
so we need to handle this as a special case when generating not-supported
test cases.
In this commit:
* Add manually written not-supported test cases for the signature
operation when exactly one variant is supported.
* Add manually written positive test cases for the verification
operation when exactly one variant is supported.
* Register that !ECDSA but DETERMINISTIC_ECDSA is not tested yet
(https://github.com/Mbed-TLS/mbedtls/issues/9592).
A commit in the framework will take care of automatically generated test cases.

Following "PSA sign/verify: more uniform error on an unsupported hash", some
error cases are detected earlier, so there is some sloppiness in test case
dependencies that is not longer acceptable.
* In test_suite_psa_crypto, one test case for a hash+sign algorithm now
returns NOT_SUPPORTED rather than INVALID_ARGUMENT when the hash is not
supported and the key is invalid.
* In test_suite_psa_crypto_se_driver_hal_mocks, some test cases now error
out before reaching the mocks rather than after when they attempt to
use an unsupported hash.

Allow imports of an ECC public key on an unsupported curve to return
INVALID_ARGUMENT rather than NOT_SUPPORTED. This can happen in our library
code in edge cases when only certain curve families are supported, and it's
acceptable.
The new code does not trigger yet, but it will be useful for a future commit
"Do run not-supported test cases on not-implemented mechanisms"
(forward port of 995d7d4c15406b0a115cadf3f5ec69becafdf20f).

Uniformly return PSA_ERROR_NOT_SUPPORTED if given an algorithm that includes
a hash, but that hash algorithm is not supported. This will make it easier
to have a uniform treatment of unsupported hashes in automatically generated
tests.
