Starting from the all.sh component created in #8962:

1. In that component, build Mbed TLS twice, in separate build directories:
   • Once with the configuration of component_build_full_psa_crypto_client_without_crypto_provider, but with some potentially problematic features disabled:
     • Disable MBEDTLS_X509_RSASSA_PSS_SUPPORT and the RSA key exchanges.
     • Disable restartable ECC.
     • Disable multithreading.
   • once with the configuration of component_build_psa_crypto_spm (and that component can be removed).
2. Run psasim with a server linked with libmbedcrypto with the SPM configuration, and a client linked with libmbed{crypto,x509,tls}.
3. Implement psa_crypto_init on the client to open a connection to the server, and mbedtls_psa_crypto_free to close the connection. The server doesn't need to maintain any client state (that will come later).
