Previously, the crypto module used built-in software implementations for a limited set of hash algorithms (md5, sha1, sha256). This prevented users from using algorithms like sha384, sha512, and sha3 family, even when the underlying OpenSSL library supported them. The change replaces built-in hash implementations with OpenSSL EVP_MD_CTX for createHash() and HMAC_CTX for createHmac(), following the webcrypto module. Algorithm lookup now uses EVP_get_digestbyname(), making any digest supported by the linked OpenSSL available to JavaScript code. The module now requires OpenSSL and is conditionally compiled, same as the webcrypto module. Builds without OpenSSL (--no-openssl) will no longer have the crypto module available. Tested with OpenSSL 3.0, OpenSSL 1.1.1w, LibreSSL 3.9.2, and BoringSSL. SHA-3 tests are skipped when the SSL library does not support them (e.g. BoringSSL). This closes nginx#1037 feature request on Github.

The change replaces built-in hash implementations with OpenSSL EVP_MD_CTX for createHash() and HMAC_CTX for createHmac(), following the pattern already established by the webcrypto module. Algorithm lookup now uses EVP_get_digestbyname(), making any digest supported by the linked OpenSSL available to JavaScript code.
