psa_wipe_key_slot can now be called on a slot in any state, if the slot's state
is PSA_SLOT_FULL or PSA_SLOT_PENDING_DELETION then there must be exactly 1 registered
reader.
Remove the state changing calls that are no longer necessary.

Replaces calls to psa_unlock_key_slot with calls to psa_unregister_read.
All instances follow a pattern of a call to psa_get_and_lock_key_slot_X,
followed by some code which reads from a slot, followed by a call to psa_unregister_read.

This does not yet implement destruction while a key is in use for psa_destroy_key;
that will be implemented in a separate pr.
(I am not sure if I am allowed to change the documentation in the include files.)

Specifically:
* Move the creation of the pointer to the copied buffer into the
DECLARE() macro, to solve warnings about potentially skipping
initialization.
* Reorder the arguments of the FREE() macro - having a different order
made it confusing, so keep the order the same throughout.

* Separate initialization from allocation.
* Rewrite description of macros to fit the new interface.
* Use a longer name to store the local copy objects, to reduce the risk
of shadowing.
* Use different names for the original and the copy. Append the suffix
'_external' to the original argument and use the previous name
for the copy.

Move the mbedtls_ecc helper functions from psa_core to psa_util.
These files are not implemented as part of the PSA API and should not
be part of the PSA crypto implementation.

Previously the return from psa_crypto_local_output_free() had a fixed
name, which meant that multiple outputs would cause redefinitions of the
same variable.

* Set swapped pointers to NULL when the buffers are freed.
* Change example name <buffer> to <input> and <output> to reduce
confusion.
* Document assumptions of FREE_LOCAL_ macros.
* Add comment on error case in FREE_LOCAL_OUTPUT(), explaining why it's
okay to mask the existing status code.

This allows us to entirely remove copying code, where the convenience
macros are used for copying.

Since we are applying hooks transparently to all tests, we cannot setup
and teardown test hooks in the tests. Instead we must do this in the
test wrappers which are used to pre-poison and unpoison memory.

From time being, domain_parameters could not be extracted
from driver. We need to return error to indicate this
situation. This is temporary and would be fixed after #6494.

This helps to prevent confusion as it avoids overloading the word
"copy" as both an action and an object.

When we are copying output, it makes sense to return
PSA_ERROR_BUFFER_TOO_SMALL since the buffer we are copying to is a user
output buffer.
