- 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.

If an error occurs, calling any function on the same operation should return
PSA_ERROR_BAD_STATE, and we were not honouring that for all errors. Add extra
failure tests to try and ratify this.

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.

Make it clear that these functions reset the number of ops, and remove
statements that say they have no effect.

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

Move to accumulate ops in context rather than attempting to read straight out
of structures due to structure ops getting reset per operation, and also
issues with _abort clearing internal data. Fix usage of size_t in structures

Add PSA_WANT_KEY_TYPE_PASSWORD and PSA_WANT_KEY_TYPE_PASSWORD_HASH to
psa/crypto_config.h, since the types PSA_KEY_TYPE_PASSWORD and
PSA_KEY_TYPE_PASSWORD_HASH are used by ECJPAKE.
The two key types are always enabled, like PSA_KEY_TYPE_DERIVE.
Add the key types to the metadata test suite as well.

The following shell command lists features that seem to be supported, but
are missing from include/psa/crypto_config.h:
```
for x in $(grep -ho -Ew '(PSA_WANT|MBEDTLS_PSA_BUILTIN)_\w+_\w+' library/psa_crypto*.c | sed 's/^MBEDTLS_PSA_BUILTIN/PSA_WANT/' | sort -u); do grep -qw $x include/psa/crypto_config.h || echo $x; done
```
This looks for PSA_WANT_<kind>_<thing> macros that gate a part of the
library, as well as their MBEDTLS_PSA_BUILTIN_<kind>_<thing> counterparts.
This is not necessarily a complete list of identifiers that must appear
in the config file, since a few features are not gated.

Some preprocessor macro definitions must have a specific expansion so that
the same macro name can be defined in different products. The definition of
having the same expansion (per the C language specification) means the same
sequence of tokens, and also the same absence/presence of spacing between
tokens.
Two macros are also defined in headers in the PSA Compliance test suite, so
the test suite would fail to build if we changed the definitions. Preserve
those definitions. Technically this is a bug in the test suite, since having
extra spaces (or even a completely different constant expression with the
same value) would still be compliant. Bug reported as

For PSA error code definitions, the specific expansion is mandated by the
PSA Status code specification and the PSA Crypto API specification. In
particular, there must not be a space between (psa_status_t) and the
numerical value (whereas K&R would put a space).

Additionally use psa_get_and_lock_key_slot_with_policy() to obtain key.
This requires making this function public. This will have to be solved while adding driver dipatch for EC-JPAKE.

Fix the PSA_XXX typos detected by check_names.py.
PSA_WANT is actually not typo, but would cause a false negative
result. So PSA_WANT is reworded to PSA_WANT_xxx.

This macro is specific to the Mbed TLS implementation and not part of
the public API, so it shouldn't used the PSA_ namespace.

The format used by the mbedtls_ecjpake_xxx() APIs and that defined by
the PSA Crypto PAKE extension are quite different; the former is
tailored to the needs of TLS while the later is quite generic and plain.
Previously we only addressed some part of this impedance mismatch: the
different number of I/O rounds, but failed to address the part where the
legacy API adds some extras (length bytes, ECParameters) that shouldn't
be present in the PSA Crypto version. See comments in the code.
Add some length testing as well; would have caught the issue.

TLS uses it to derive the session secret. The algorithm takes a serialized
point in an uncompressed form, extracts the X coordinate and computes
SHA256 of it. It is only expected to work with P-256.
