Define algorithms for PureEdDSA and for HashEdDSA, the EdDSA variants
defined by RFC 8032.
The encoding for HashEdDSA needs to encode the hash algorithm so that
the hash can be calculated by passing PSA_ALG_SIGN_GET_HASH(sig_alg)
to psa_hash_compute() or psa_hash_setup(). As a consequence,
Ed25519ph (using SHA-512) and Ed448ph (using SHAKE256) need to have
different algorithm encodings (the key is enough to tell them apart,
but it is not known while hashing). Another consequence is that the
API needs to recognize the Ed448 prehash (64 bytes of SHAKE256 output)
as a hash algorithm.

Add an elliptic curve family for the twisted Edwards curves
Edwards25519 and Edwards448 ("Goldilocks"). As with Montgomery curves,
since these are the only two curves in common use, the family has a
generic name.

Add missing PSA_WANT_CCM/GCM/CMAC. This completes
the set of PSA_WANT config options given the
current support of PSA crypto in Mbed TLS.

When these names were changed, the definition got misaligned with the
rest of the fields. Fix this alignment.

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,
depending on the inputs to psa_aead_set_lengths().

An earlier commit fixes the names of the PSA_WANT_ECC_ macros. Update
the crypto_config.h file to match these new names.

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.
