The hash driver entry points (and consequentially the hash driver core)
are now always compiled on when PSA_CRYPTO_DRIVER_TEST is turned on.

Drivers (both built-in and external) need to declare their context
structures in a way such that they are accessible by the
to-be-autogenerated crypto_driver_contexts.h file. That file lives in
include/psa, which means all builtin driver context structure
declarations also need to live in include/psa.

psa_aead_generate_nonce() could generate a nonce of up to 13 bytes,

Apparently there's a goal to make the PSA Crypto core free from
dynamic memory allocations. Therefore, all driver context structures
need to be known at compile time in order for the core to know their
final size.
This change defines & implements for hashing operations how the context
structures get defined.

Fix places where Doxygen documentation uses \p to refer to a parameter
name and where the name used did not match the actual parameter name.
I used the following script to detect problematic cases:
```
perl -w -ne 'if (eof) { $. = 0; } if (m!^/\*\*!) { $in_doc = 1; %param = (); %p = (); } if (m!\*/!) { foreach $name (keys %p) { if (!$param{$name}) { foreach $line (@{$p{$name}}) { print "$ARGV:$line: $name\n" } } } $in_doc = 0; } if ($in_doc) { if (/\\param(?: *\[[^\[\]]*\])? +(\w+)/) { $param{$1} = 1; } foreach (/\\p +\*?(\w+)/) { push @{$p{$1}}, $.; } }' include/psa/*.h
```
This commits fixes all the remaining occurrences under include/psa,
which were just trivial name mismatches.

In Doxygen documentation, use \c rather than \p when discussing
something that isn't a parameter of the current macro or function.
Where needed, explain what the thing is.

PSA_KEY_TYPE_RAW_DATA and PSA_KEY_TYPE_DERIVE are always supported.
Make this explicit by declaring PSA_WANT_KEY_TYPE_RAW_DATA and
PSA_WANT_KEY_TYPE_DERIVE unconditionally. This makes it easier to
infer dependencies in a systematic way.
Don't generate not-supported test cases for those key types. They
would always be skipped, which is noise and would make it impossible
to eventually validate that all test cases pass in at least one
configuration over the whole CI.
Don't remove the exception in set_psa_test_dependencies.py for now, to
get less noise in dependencies. This may be revised later if it is
deemed more important to be systematic.

PSA defines CBC with no padding, and CBC with PKCS7 padding. The bare
"ALG_CBC" is not defined, so remove this definition.

Make sure MBEDTLS_PSA_CRYPTO_CLIENT is defined
when MBEDTLS_PSA_CRYPTO_C is defined and guard
PSA client code only with MBEDTLS_PSA_CRYPTO_CLIENT.
The definition of MBEDTLS_PSA_CRYPTO_CLIENT is done
in crypto_types.h before the definition of
psa_key_attributes_t. That way as PSA crypto client
code is related to key attributes we can be quite
confident that MBEDTLS_PSA_CRYPTO_CLIENT will be
defined when needed.

Attempting to create an ECC key with a curve specification that is not
valid can plausibly fail with PSA_ERROR_INVALID_ARGUMENT ("this is not
a curve specification at all") or PSA_ERROR_NOT_SUPPORTED ("this may
be a curve specification, but not one I support"). The choice of error
is somewhat subjective.
Before this commit, due to happenstance in the implementation, an
attempt to use a curve that is declared in the PSA API but not
implemented in Mbed TLS returned PSA_ERROR_INVALID_ARGUMENT, whereas
an attempt to use a curve that Mbed TLS supports but for which support
was disabled at compile-time returned PSA_ERROR_NOT_SUPPORTED. This
inconsistency made it difficult to write negative tests that could
work whether the curve is implemented via Mbed TLS code or via a
driver.
After this commit, any attempt to use parameters that are not
recognized fails with NOT_SUPPORTED, whether a curve with the
specified size might plausibly exist or not, because "might plausibly
exist" is not something Mbed TLS can determine.
To keep returning INVALID_ARGUMENT when importing an ECC key with an
explicit "bits" attribute that is inconsistent with the size of the
key material, this commit changes the way mbedtls_ecc_group_of_psa()
works: it now works on a size in bits rather than bytes, with an extra
flag indicating whether the bit-size must be exact or not.
