Replaces psa_lock_key_slot and psa_unlock_key_slot.
Future commits will remove the calls to locking/unlocking functions,
and add calls to registering/unregistering functions.

Remove psa_is_key_slot_occupied, any function which calls this can just check
the state variable instead.
Replace psa_is_key_slot_locked with psa_key_slot_has_readers.
References to the now removed functions are changed in future commits.

Remove the `status` field and replace with the `state` field.
Remove the `lock_count` field and replace with the `registered_readers` field.
Add documentation which describes how and why these fields are to be used.

Legacy CCM and GCM can work even when AES_C is not defined thanks
to the block_cipher module, so we can relax guards in
cipher_wrap.

This commit also updates test_suite_pkparse.data file adding
MBEDTLS_CIPHER_C dependencies whenever PKCS[5/12] is used.

Directly export the public part of a key pair without having to go through
intermediate objects (using mbedtls_ecp_point_write_binary would require a
group object and a point object).

Set the public key in a key pair. This complements mbedtls_ecp_read_key and
the functions can be used in either order.
Document the need to call check functions separately.

Sometimes you don't need to have all the parts of a key pair object. Relax
the behavior of mbedtls_ecp_keypair so that you can extract just the parts
that you need.

Add a simple function to get the group id from a key object.
This information is available via mbedtls_ecp_export, but that function
consumes a lot of memory, which is a waste if all you need is to identify
the curve.

And use it in the non-PSA version of mbedtls_pk_sign_ext()
to bypass checks that didn't succeed when used by TLS 1.3.
That is because in the failing scenarios the padding of
the RSA context is not set to PKCS_V21.
See the discussion on PR #7930 for more details.

This makes the function always available with its
its implementation depending on MBEDTLS_USE_PSA_CRYPTO.
Related dependencies and tests are updated as well.
Fixes#7583.

Old versions of clang don't support this pragma, so we have to assume
that the user will have set the flags.

New defines, which are shared with the pkparse module, lack the
new line so we manually add it when invoking
mbedtls_pem_write_buffer().

GCC with TSan + O3 causes an error where it claims key_len and iv_len
may be used uninitialised. This is, as far as I can tell incorrect (the
only way it could not be set is in the error case, and then it is not
used), however the simplest option seemed to be just to fix it.
