Fix a missing dependency in configuration symbol test enumeration: PSA_WANT_xxx is only meaningful when PSA crypto is enabled. This isn't needed in TF-PSA-Crypto where all crypto goes through PSA anyway, but it is relevant in 3.6 and harmless (as long as we keep MBEDTLS_PSA_CRYPTO_CLIENT at least as an internal symbol) in TF-PSA-Crypto.
