In TF-PSA-Crypto 1.0 and Mbed TLS 4.0, cryptographic mechanisms can only be configured through PSA_WANT_xxx options, not through legacy options like MBEDTLS_SHA256_C, MBEDTLS_ECDH_C, etc.

The goal of this issue is to clean up all public documentation that refers to legacy options.

Preliminary: remove both MBEDTLS_USE_PSA_CRYPTO and MBEDTLS_PSA_CRYPTO_CONFIG from the public interface, which is ongoing at the time I write this. These options together made things complicated, but we now have a clean slate.
