Draft: Update OpenSSL

DO NOT MERGE YET - fingerprint not working

This MR updates the vfs0090.c file to be compatible with OpenSSL 3.0 by replacing all deprecated OpenSSL functions with their modern equivalents. Here's a summary of the changes made:

1. Updated Function Signatures

• Changed load_key() function to return EVP_PKEY* instead of EC_KEY*
• Updated sign2() function to accept EVP_PKEY* instead of EC_KEY*

2. Replaced Deprecated OpenSSL Functions

• EC_KEY_new_by_curve_name() → EVP_PKEY_fromdata() with OSSL_PARAM_BLD
• EC_KEY_set_public_key_affine_coordinates() → OSSL_PARAM_BLD_push_BN() for X/Y coordinates
• EC_KEY_set_private_key() → OSSL_PARAM_BLD_push_BN() for private key
• EC_KEY_check_key() → EVP_PKEY_check()
• ECDSA_do_sign() → EVP_DigestSign()
• EVP_PKEY_set1_EC_KEY() → Direct use of EVP_PKEY from load_key()
• ECDH_compute_key() → EVP_PKEY_derive()
• EC_KEY_get0_public_key() → Eliminated by using EVP_PKEY directly

3. Added Required Headers

• Added #include <openssl/param_build.h>
• Added #include <openssl/core_names.h>

4. Updated Parameter Names

• Used correct OpenSSL 3.0 parameter names: OSSL_PKEY_PARAM_EC_PUB_X, OSSL_PKEY_PARAM_EC_PUB_Y, OSSL_PKEY_PARAM_PRIV_KEY

5. Modernized Key Operations

• Added the missing autoptr cleanup function definition
• Replaced low-level EC_KEY operations with high-level EVP_PKEY operations
• Used OSSL_PARAM_BLD for constructing key parameters
• Implemented proper error handling for all new OpenSSL 3.0 functions
