The EVP_KDF API was added in OpenSSL 3 to properly support KDF algorithms, such as HKDF. It is recommended that KDF operations migrates from the EVP_PKEY API to this new API. The built-in providers still support the EVP_PKEY for back compat, but third party provider might not do it (SymCrypt looking at you).
This PR implements HKDF using the EVP_KDF API when using OpenSSL 3.
