Define the dependency symbols PSA_WANT_ALG_ECDSA_ANY and
PSA_WANT_ALG_RSA_PKCS1V15_SIGN_RAW as de facto synonyms of
PSA_WANT_ALG_ECDSA and PSA_WANT_ALG_RSA_PKCS1V15_SIGN respectively: if
either one is requested, the other is set.
This makes it easier to systematically determine the dependencies of
an algorithm.

Add missing PSA_WANT_CCM/GCM/CMAC. This completes

Fix SEC to SECP as the curve name. This fixes failing tests that

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.

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.

With the else branch commented out, both lines are unnecessary. We
could check for the invalid configuration in the future, once tests were
made to exclude this combination.

There is no PSA ALG_ECB, only ALG_ECB_NO_PADDING. Fix one incorrect
declaration, and remove another that is just redundant.

Only define MBEDTLS_CIPHER_MODE_CBC if one of the CBC modes is requested
and everything isn't covered by an accelerated version. This keeps this
from being defined in cases where everything needed would be
accelerated.

If any of the software block ciphers are selected, define an internal

Add checks for PSA_WANT_KEY_TYPE_CHACHA20, both with and without
MBEDTLS_PSA_CRYPTO_CONFIG. This only adds support for the ciphers
itself, presumably as a stream cipher (and not yet AEAD).

Even if there is an accelerated version of a (block) key type, enable
the SW implementation if there are block modes that don't have
acceleration.

Add additional ifdef checks in the PSA config to detect when an
algorithm is entirely implemented in hardware. If there is any
combination of cipher and padding type that is not supported by the HW
acceleration, enable the SW acceleration.

Add support for supported block modes using the PSA crypto config.

Removed unecessary checks on the ALG_SHA_224 and ALG_SHA_384 since
those are handled in config_psa.h by ensuring the correct _C is
included. Reformatted config_psa.h to be alphabetical and made the
assignments line up correctly for consistency. Fixed the guards
for ALG_SHA_224 and ALG_SHA_384 to be correct in the crypto library
source.

When MBEDTLS_PSA_CRYPTO_CONFIG is disabled, if an Mbed TLS crypto
feature is enabled, declare the corresponding PSA feature as enabled,
in addition to enabling its software implementation. This is necessary
for code that uses PSA APIs and relies on PSA_WANT_xxx symbols to know
which features are enabled (application code, our library code using
MBEDTLS_USE_PSA_CRYPTO, our test dependencies, etc.).

Moved from doing the dependency checks for MBEDTLS_PSA_BUILTIN to
