Add a new macro `LOCAL_OUTPUT_ALLOC_WITH_COPY` to support the output buffer
handling of the multipart operations like `psa_cipher_update`. This will
allocate a local buffer and copy the content of the original buffer.

The signature and naming of the Montgomrey initialisation function in
development and in the LTS was different. Align them for easier
readability and maintenance.

So far we needed it only locally here, but we will need calculating RR
for safe unblinding in RSA as well.

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.
Signed-off-by: David Horstmann <david.horstmann@arm.com>
* 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.

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.

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.

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