Update this based on the output of the generator script. The Brainpool
curves are now supported, since they are spelled properly in the config.

psa: ecdsa: Prefer NOT_SUPPORTED error code
had an incorrect merge conflict resolution. Correct this, allowing the
test "PSA sign: invalid algorithm for ECC key" to pass again.

Fix SEC to SECP as the curve name. This fixes failing tests that
verified the config option was working.

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

Now that PSA crypto config supports the new PSA_WANT_ECC_xxx defines,
change the psa-specific test suites to use these new names.

Use the names as described in
`docs/proposed/psa-conditional-inclusion-c.md which use a transform
like: SECP256R1 -> SECP_R1_256. The CURVE25519 and CURVE448 become
MONTGOMERY_255 and MONTGOMERY_448.

For each curve defined MBEDTLS_ECP_DP_xxx_ENABLED, we have a
corrsponding PSA config define PSA_WANT_ECC_xxx. Along with that is a
value MBEDTLS_PSA_ACCEL_ECC_xxx which can be used to allow HW
acceleration of that particular curve.
If the PSA config requests an unaccelerated curve, the corresponding
MBEDTLS_PSA_BUILTIN_ECC_xxx will also be defined.
This commit defines these for all curves currently defined, with the
defines working in either direction, depending on whether
MBEDTLS_PSA_CRYPTO_CONFIG is defined.

mac size is previously checked to not be less than 4, so it can't be zero

Memsan build was reporting a false positive use of uninitialised memory
in x509_crt.c on a struct filled by an _stat function call. According to
the man pages, the element reported has to be filled in by the call, so
to be safe, and keep memsan happy, zero the struct first.

When ECDSA is not supported by the library, prefer
to return NOT_SUPPORTED than INVALID_ARGUMENT when
asked for an ECDSA signature.

Move the check that ECDSA is supported from the
caller of the function responsible for Mbed TLS
ECDSA signatures to this function, namely
mbedtls_psa_ecdsa_sign_hash().
This makes the caller code more readable and is
more aligned with what is expected from a
sign_hash() PSA driver entry point.
Add a negative test case where a deterministic
ECDSA signature is requested while the library
does not support deterministic ECDSA.

Reworked the validation of MAC algorithm with the used key type by
introducing psa_mac_key_can_do, which guarantees that PSA_MAC_LENGTH can
be called successfully after validation of the algorithm and key type.
This means psa_get_mac_output_length is no longer required.

Comparing algorithm with its FULL_LENGTH_MAC version doesn't work in
cases where algorithm is a wildcard. Wildcard input is not specified in
the documentation of the function, but in order to test the function
using the same test as PSA_MAC_LENGTH we're mimicking that behaviour here.

Avoid code duplication. Also update the guarantees made by the function
doc to match the guarantees given by PSA_MAC_LENGTH.

This makes it more in-line with how psa_key_policy_permits works. It
also adds consistency: the intersection of MAC with default length and
MAC with exact-length is now computed correctly in case the exact length
equals the default length of the algorithm when used with the given
key type.
