f8e5b56ad8 Fix get_num_ops internal code.
Previously calling get_num_ops more than once would have ended up with ops
getting double counted, and not calling inbetween completes would have ended up
with ops getting missed. Fix this by moving this to where the work is actually
done, and add tests for double calls to get_num_ops().

de1114c883 Fix {sign|verify}_get_num_ops
Move the obfuscation of the internal library only returning a delta of ops done
into the driver wrapper, thus meaning driver wrapper and API call both return
absolute values of work done. Document the differences at the internal
implementation level.

f9c91a7fb5 Store the hash, rather than the pointer
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.

ed73355d2e Make \retval commands non-empty
Pacify Clang >=15 which complained:
```
include/psa/crypto.h:91:23: error: empty paragraph passed to '\retval' command [-Werror,-Wdocumentation]
 * \retval #PSA_SUCCESS
   ~~~~~~~~~~~~~~~~~~~^
```

This commit performs the following systematic replacement:
```
perl -i -0777 -p -e 's/([\\@])(retval +\S+)\n(?! *\*? *([^\n \\*\/]|\\[cp]\b))/$1$2 ${1}emptydescription\n/g' $(git ls-files '*.[hc]' '*.function' '*.jinja')
```
i.e. add an `\emptydescription` argument to `\retval` commands (or
`@retval`, which we don't normally used) that are followed by a single word,
unless the next line looks like it contains text which would be the
description.

Add test driver support for opaque key import
-Add test driver support to import/export while wrapping keys
 meant to be stored in the PSA core as opaque( emulating an
 SE without storage ).
-Export validate_unstructured_key_bit_size as
 psa_validate_unstructured_key_bit_size, thereby changing its scope.
-Improve the import/export test cases in test_suite_psa_crypto to also
 cover opaque keys, thereby avoiding duplication.

ea0f8a6d1a psa: se: Create key context in SE key slots
In key slots containing the description of a key of a
dynamically registered Secure Element (SE), store the
key slot number in a key context as defined in the
PSA driver interface for opaque drivers.

That way transparent key data and slot numbers are
, in a key slot, both stored in a dynamically allocated
buffer. The `data` union in structures of type
psa_key_slot_t to distinguish between the storage of
transparent key data and slot numbers is consequently
not necessary anymore and thus removed.

This alignement of some part of the code dedicated to
dynamically registered SE with the PSA driver interface
specification is done to ease the support of both
dynamically registered and statically defined secure
elements.

3ea0ce450f Separate 'import' from 'load into slot'
Now that there's a validate_key entry point for drivers, it becomes
much more important to separate the import action (where a key needs
to be validated) from the load action (where a key has been
previously validated, and thus re-validating it would be a waste of
time).

This also exposes why not storing the 'bits' attribute persistently
was a bad idea. The only reason there's a rather large function to
detect bit size is because loading from persistent storage requires
it.
