fix PR9302 backporting issues
- psa_crypto_helpers.h
mbedtls-3.6 branch misses some crypto client changes that has
been done in the development branch since the LTS release. Therefore
CRYPTO_C guard here is more accurate than CRYPTO_CLIENT.
- entropy.h
In the development branch MBEDTLS_ENTROPY_BLOCK_SIZE is defined
when PSA_WANT_ALG_SHA_[256/512] is defined while in the mbedtls-3.6
branch is guarded by MBEDTLS_MD_CAN_SHA[256/512] which is slightly
different. Since MBEDTLS_ENTROPY_BLOCK_SIZE is used in some tests's
data files, we need to have it defined also if the related test
is skipped. Therefore we add the PSA_WANT_ALG_SHA conditions together
with the MBEDTLS_MD_CAN_SHA ones to mimic the development behavior.
