Add dependencies to metadata validation tests

If some algorithms are excluded in the build, it's ok for the corresponding
macros not to give the correct results. Therefore the corresponding test cases
should depend on the implementation of the algorithm. For example, it's ok for
PSA_HASH_MAX_SIZE to be less than PSA_HASH_SIZE(PSA_ALG_SHA_512) if we build
without SHA-512 support, and we indeed do this. It's even ok for an
implementation to return 0 for PSA_ALG_IS_HASH(PSA_ALG_SHA_512) if it doesn't
support SHA-512; we return 1 anyway but the tests are less
implementation-specific if we don't enforce it.

This commit adds dependencies on symbols that don't exist in Mbed TLS,
for algorithms that Mbed TLS doesn't implement. These are:
MBEDTLS_SHA512_256 for SHA-512/256, MBEDTLS_SHA3_C for SHA-3,
MBEDTLS_DSA_C and MBEDTLS_DSA_DETERMINISTIC for DSA, and
MBEDTLS_ECP_DP_xxx_ENABLED for elliptic curves that have a PSA
encoding but are not supported in Mbed TLS.
