Access the fields of `psa_key_attributes_t` directly rather than through the
`core` field. This makes the `core` field obsolete.
This commit is fully automated:

Now that a key slot contains the full `psa_key_attributes_t, the temporary
local variables holding a copy of core attributes read from the slot are no
longer needed.

Switch `psa_key_slot_t` to the full `psa_key_attributes_t`, now that this
structure only has psa_core_key_attributes_t`.
To minimize the diff without breaking the build much, temporarily make
`psa_key_attributes_t` contain either the `core` field or all the fields.
This allows both things like `slot->attr.core.type` and `slot->attr.type`
to exist. The build breaks with compilers that don't support anonymous
unions and structs, which are only standard C since C11.

Move the `slot_number` field of `psa_key_attributes_t` to
`psa_core_key_attributes_t`. This makes ``psa_core_key_attributes_t` core`
the sole field of `psa_key_attributes_t`. This paves the way to unifying
the two structures.

Re-restore mbedtls_x509_string_to_names() to public as our example
programs use it, and it is the reverse of mbedtls_x509_dn_gets().
Add a docstring, so that it is a properly documented public function.

It means that mbedtls_psa_get_random() goes through the PSA interface
all the times. Fallbacks to CTR_DRBG or HMAC_DRBG are still possible,
but that depends on how the crypto provider is built.

Remove the ability to select a custom public exponent via domain parameters
in RSA key generation. The only way to select a custom public exponent is
now to pass custom production parameters to psa_generate_key_ext().
A subsequent commit will remove domain parameters altogether from the API,
thus this commit does not bother to update the documentation.

The setup calls are the only calls to use a key ID.
The key is then copied into the operation object,
all future API calls use the copy instead of the key in the slot.
Simultaneous API calls on the same operation object are not thread-safe.

The only interaction with key IDs here is in the changed function.

One can input a key using a key identifier through the two changed functions.
Inputted keys are copied into the operation object.
Any material inputted in byte form is separate to the key slot system.
Outputting a key is threadsafe as per the key loading work.
The verification API is yet to be implemented.
Simultaneous API calls on the same operation object are not thread-safe.

Within setup we create a copy of the key and put it in the operation field.
After setup, we only ever use the new copy,
and do not interact with any key slots.
Therefore we need only register as a reader of the key during setup,
then unregister after we stop accessing the key.
Simultaneous API calls on the same operation object are not thread-safe.

We copy the key from a slot to the operation object in _start.
_complete and _abort do not access any key slots, instead using
the local copy.
Concurrently using the same operation object is not thread-safe.

This function should be internal, being exposed only via functions like
mbedtls_x509write_crt_set_subject_name().
