sha256: avoid functions deprecated in OpenSSL 3+

Browse Source 
OpenSSL 3+ deprecates the SHA256_Init, SHA256_Update, and SHA256_Final
functions, leading to errors when building with `DEVELOPER=1'.

Use the newer EVP_* API with OpenSSL 3+ despite being more
error-prone and less efficient due to heap allocations.
